Diamond Testing

Diamond Testers - How They Work

S ometimes one needs to get a diamond tested to ensure it is, in fact a real dia-mond. Artificial and synthetic diamonds

are so close to the original nowadays that in order to be able to spot the difference one needs to get a diamond tester to check the dia-mond to see if it is genuine. Some years ago, before synthetic diamonds were produced a diamond tester called a thermal detector was used. This tester has a metal tip which is heat-ed to a high degree and then the tip is applied to the diamond being checked. A transfer of heat occurs and if the read back from the dia-mond to the tester matches then you could say you have a real diamond on your hands. How-ever this is not such a good test these days as a synthetic diamond will show the same readout as a genuine diamond so more sophisticated tests are used these days to overcome this problem. Diamond simulants, or synthetics usually come as synthetic cubic zirconia, syn-thetic strontium titanate, YAG (yttrium alu-minium garnet) and GGG (gadolinium gallium garnet). Currently there are four types of diamond test-er used these days. Ceres Diamond Tester, the Rayner Diamond Tester, the Diamond Pen, used by the GIA and Fluorescence Diamond Testing. Ceres Diamond Testing The Ceres Diamond tester works on the princi-ple that diamonds conduct heat at a high ther-mal conductivity. No diamond simulants will conduct heat so well and are typically very poor conductors of heat. So by applying this principle one can easily sort out the genuine

diamond from the simulant.

In use it needs to be apply correctly of course as metals such as silver, gold and platinum will conduct heat and so if you touch the ring a dia-mond is set in you will get a high reading. Also moissanite's thermal conductivity is similar to diamond so one should conduct a moissanite test also to a diamond one has tested to be sure it is not a moissanite. The Ceres will, however spot cubic zirconium as the thermal conductivity is very different to a genuine diamond. It is a very delicate instrument and should be used with care to ensure you do not damage the tip and also get an accurate reading. Rayner Diamond Tester The Rayner Diamond Tester is a more expen-sive instrument and designed for the profes-sional diamond dealer or jeweller. The Rayner works similar to the Ceres but is more exact. One needs to be in the profession in order to obtain a Rayner Diamond tester. Diamond Pen The Gemmological Institute of America (GIA)

~ Famous Diamond Quotes ~ "No gold-digging for me; I take diamonds! We may be off the gold standard someday." Mae West How prophetic! “I think men who have a pierced ear are better prepared for marriage. They've experienced pain and bought jewelry. Rita Rudner “Jewelry takes people's minds off your wrinkles.” Sonja Henie “Will the people in the cheaper seats clap your hands? And the rest of you, if you'll just rattle your jewelry.” John Lennon

use a diamond tester they have developed themselves. This does not work on the ther-mal principle but on the property of non ab-sorption of a special liquid when applied to a diamond. A special pen is used rather like a fountain pen and a drop of a greasy type liq-uid is placed by the pen on the diamond sur-face. On a diamond it will leave a visible mark but on any other kind of stone the liquid beads up and does not leave any marks. Fluorescence Diamond Testing A Fluorescence diamond tester will test the fluorescence of a diamond. Under long-wave ultra-violet light, diamonds will show a very varied degree of fluorescence since all dia-monds have a fluorescence level measured from one to five and each falls somewhere on that scale but as each stone is different doing a comparison it is easy to see. Synthetic dia-monds all have the same florescence so can be clearly seen to be synthetic. Under X-rays, almost all diamonds show a blue fluorescence and a brief exposure on film will show dia-monds to be far more transparent to X-rays

than any other stone. This test, however, alt-hough considered a decisive test, should be done in conjunction with either the thermal or Pen method also. Immersion Contrast Method One can also use the Immersion Contrast Method. When light is placed over simulant stones such as Strontium titanate, YAG, GGG and CZ, for example and immersed in di-iodomethane (methylene iodide; a high densi-ty liquid with a refractive index of 1.742) or Refractometer contact fluid (RI 1.81), the dif-ferent stones show differing patterns. All ex-cept strontium titanate will show a dark ring diminishing in width as their refractive index approaches near to that of the liquid. This is a definite visual indication of differentiation between diamond and its simulant. So the above shows how the principle dia-mond testers work. It is important to ensure that one's diamonds are the real McCoy and this can easily be done by any of the Diamond Testers above.

Clarity Enhanced Diamonds Life-time War-ranty Clarity enhancement is a process in the manu-facturing of diamonds. They enhance the clari-ty of the finished diamond by inserting a sub-stance into the surface imperfections of the di-amond which makes them invisible. This pro-cess improves the clarity grade by an average of two grades.

Not every diamond can be clarity enhanced because only specific flaws can be fixed. Actu-ally only one out of every 500 diamonds is a candidate for clarity enhancement.

The clarity stated in the EGS certificate indi-cates the current clarity after enhancement was

done. This process is well established, and it is in use for more than ten years.

Diamonds USA state that the diamond clarity-enhancement process should last forever, how-ever care must be taken not to use a direct torch flame on the diamond when setting. In any case, they give a life time warranty for clarity enhanced diamonds and will repair the enhancement free of charge should any prob-lems arise. They claim never to have received a single complaint about our C.E diamonds at the time of writing this. The Kimberley Process Diamonds-USA state that, “… as the global diamond industry has a zero-tolerance policy toward conflict diamonds … we only purchase rough diamonds with a Kimberly certificate and through suppliers who utilize standards established by the Kimberley Process. All our diamonds are guaranteed to be conflict free. We will continue to support and promote any process that works to uphold legitimacy in the diamond trade.”

How to Buy Diamonds

Before you set out to buy a diamond ring, ear-rings or a pendant for example, it is a good idea to find out as much information on how to buy diamonds as possible.

There are 5 factors in knowing how to buy dia-monds

• How much is your budget • What is the diamond for you • What is the right price to pay for diamonds • Where to buy diamonds at the right price, and • How to get a good deal

How much is your Budget This can depend on a number of factors. What is the purpose of buying a diamond? Is it a dia-mond engagement ring, a diamond wedding ring? Or perhaps just a gift for another. Maybe it is simple you want some diamond earrings or a pendant you would like to have.

DeBeers have promoted the idea that two months’ salary is a good benchmark for how much to spend on a diamond ring. This is all well and good but if you are on little or no in-come this is really out of the question. At the other end of the scale if you are extremely wealthy then two months ‘salary’ may seem a paltry figure to spend on a large rock!

For the average person however, this is proba-bly as good a benchmark as any.

Another issue is how one intends to pay for it. If you’re using a credit card you need to factor in the additional costs. Interest and, some-times, an extra charge should be included in the cost. If possible it is always ideal to pay cash up front. Apart from the fact that one is not running up a debt and additional costs, one

can sometimes do a deal and get a discount by paying cash up front. Not only that, there is also some extra leeway to perhaps buy a more expensive diamond.

All these points can make a difference to the cost and how much of your budget goes to pay for those costs.

What is the Diamond for you? Having established what you can spend, you can now look at what sort of diamond you can get for the price.

It is a good idea to have what you want in mind before you go looking for a diamond or diamonds.

What do you want in a diamond? Is it a ring, earring, pendant or even a necklace or brace-let? As a general rule the more diamond weight you buy the more expensive it or they will be. A single large diamond per carat weight is going to cost more than a number of smaller diamonds adding up to the same carat weight., This is because the larger a diamond is the more rare it is and you pay for that rarity. This is why 30 carat diamonds cost considera-bly more per carat than say a 1 or 2 carat dia-mond. Whereas a 2 or 3 carat diamond may cost a few thousand, a 30 carat diamond is go-ing to cost in the millions.

You might, then, want to consider buying a ring with a number of smaller diamonds in it. That will enable you to have more diamonds for your buck, so to speak.

So as well as the price of diamonds varying depending on the weight of the diamond there is also the quality to consider.

Which brings us to what is the right price to pay for a diamond?


Price of Diamonds

What is the right price to pay for dia-monds? Diamond prices are based on four important characteristics of diamonds.

These are Cut, Color, Clarity and Carat Weight.

The first is the cut. It is the cut that determines the brilliance of the diamond. If the diamond is cut correctly then it will have excellent bril-liance. Poorly cut and the brilliance will be less. A poorly cut diamond will sell for less of course.

There are 8 main cuts of diamonds.

Round Brilliant Emerald Cut Princess Cut Heart Cut Oval Cut Marquise Cut Pear Cut Round Brilliant

The second important characteristic is the dia-mond color.

Diamonds are graded into 13 colors or tints with pure white being the top, to a poor yellow being the bottom. It is important to know the color of the diamond you are going to buy as that will make a tremendous difference to the price of the diamond. Clarity is the next grading method with dia-monds, and indicates the amount of blemishes and inclusions (imperfections) in the diamond. Most imperfections are too small to affect the performance of a diamond but in the cheaper diamonds, you can find clouds of imperfec-tions. These affect the ability of the diamond to transmit light and so produce less sparkle. In addition if there are any cracks in the dia-

mond this will make it prone to fracture and even break. This is why it is important to ex-amine a diamond free of any clasp or prongs. present in gem-quality diamonds do not affect the diamonds’ performance or structural integ-rity.

Some diamond experts consider inclusions and blemishes can be advantageous as it means that diamond can be recognized. Despite this “flawless” diamond is that which commands the best price.

Most people are aware of what carat weight means. Although the other qualities are often overlooked, the carat weight is very under-stood. For those unfa-miliar, the carat is a unit of mass used for measuring gems and pearls. One carat is di-vided into 100 parts. Each part is called a point. A diamond that weighs one (1.00) carat also weighs 100 points. A carat weighs .2

grams. It is probably considered the most important characteristic way of valuing diamonds.

Where to buy diamonds at the right price Also should be factored in is where and how you buy them. You can buy diamonds and dia-mond jewelry from many places. The shop in the Mall, professional jewelers, at auctions where you are present or online, even adver-tisements or jewelery clubs.

Very popular nowadays is the online jeweler where you can look at literally thousands of diamonds and diamond jewelery of every type and description. The advantage here is that it

helps you to choose what you want or what is closest to what you are looking for.

If you have established how much you can af-ford and basically what you want, it is a simple matter, then, of scouring the net and shops in hour area to find those diamonds that match your needs.

Doing a comparison of the various diamond jewelery sites will help to find out the best price.

The disadvantage of buying diamonds of the net is that you do not get to actually see the diamonds until you have them in your home. They can look quite different to what is shown on the screen, partially because they may not be the same ones and partially because each screen and computer is going to sow the dia-monds differently.

As a result you do need to ensure that the jew-elers and dealers you are checking have a suit-able policy for returning diamonds that are not as described or even quite different.

One should ensure that one gets a certificate with the diamond to show the characteristics of the diamond, cut, color, clarity and carat weight so you:

a. Know you are getting what you paid for and b. Can insure the diamonds for their replace-ment value.

How to get a good deal buying diamonds Once you have decided on a diamond or dia-mond jewelery that is within your budget is what you want and the price for that diamond or diamonds is right the next thing is to work on getting a discount or a better deal. These days diamond merchants, jewelers and dealers are keen to sell. There is a slower economy, more competition and diamonds are not always as expensive as some would have you believe. The premium or retail mark up is quite large so there is leeway for negotiation, particularly with the slower moving larger diamonds.

You can ask what the best price is for a stone or piece, You have an advantage if you are paying cash. You can ask, then, what price would you consider for a cash deal? You can offer a comparison with another site, jeweler etc. And ask if they can match, or to get your business offer a better deal.

There are many ways of negotiating a better deal but importantly never be afraid to ask. You might be surprised at what you can get.

Price of Diamonds

Diamond Glossary

H ere are some common words used in the Diamond Industry and in this newsletter.

4Cs Diamonds are graded and priced according to what is universally referred to as the "4C's". They are Cut, Color, Clarity and Carat Weight. Below an explanation of each of the 4Cs: Appraisal A valuation of property by the estimate of an authorized person. With diamonds the apprais-al is a written estimate of the approximate re-tail replacement value of diamond jewelry, which may be used for insurance coverage or other purposes. It is not the same as a grading report, which evaluates a diamond's character-istics (such as cut, clarity, carat, symmetry, etc.) only. Blemish A scratch or abrasion on the surface of a dia-mond. Provided they do not interfere with the symmetry of the stone and do not interfere with light in the stone they are not considered important. Brilliance brilliance is the white light that is reflected through the top of a diamond. This can be in-

crease by the diamond being cut to the correct proportions to take advantage of the reflection of light from the facets to the brilliance. Brilliant Cut A Brilliant Cut, sometimes called the Ameri-can Brilliant, is a 58-facet round diamond, This shape and faceting arrangement is de-signed for maximum brilliance, sparkle and beauty and is perhaps the most popular shape. Carat Perhaps everyone know the term carat. The basic unit of weight for a diamond. A carat is equal to 200 milligrams, or one-fifth of a gram. It is said that the word is derived from the word carob. In early India the carob bean was used for measuring the weight of gems as eve-ry carob seed weighs exactly the same. Clarity Clarity is the term given to indicate the purity of a diamond. Most diamonds have minute im-perfections and the clarity is the way of grad-ing the purity depending on the number of im-perfections the diamond has or does not have. Cloud A cluster of very small inclusions inside a dia-mond that give a cloud effect. Tiny clouds will not interfere with the flow of light, but large or numerous clouds can affect brilliance. Color Diamonds are traditionally thought of as white or clear. But diamonds in fact do have color and this can be graded.

Price of Diamonds

Crown The crown is the top section of a diamond, above its widest point, or girdle, that comprises the table, and the star-, bezel- and upper-girdle facets. Culet A facet on the very bottom of a diamond. It is best to have a small or medium culet. A large culet will make it look like there is a hole in the bottom of the stone due to leakage of light. Absence of a culet makes the point of the dia-mond more easily damaged or chipped. Cut This describes the shape of the diamond. There are basically eight cuts of diamond.

Round Brilliant Emerald Cut Princess Cut Heart Cut Oval Cut Marquise Cut Pear Cut Round Brilliant

Some of the most popular diamond cuts in-clude Heart, Emerald, Marquise (Oval with pointed ends), Oval, Pear, and Princess with the Round Brilliant (R/B) probably being the most popular. Depth % (percentage) The height of a diamond (measured from the culet to the table) divided by the width of the diamond. The depth % is critical to creating brilliance and fire in a diamond. A depth % that is too low or too high will cause light to leak out of the stone, causing the diamond to lose sparkle. Depth

The height of a diamond (measured from the culet at the very bottom to the large table facet on the top). Diamond The simplest of all the gemstones consisting of pure crystallized carbon. A diamond crystalliz-es under enormous pressure deep beneath the earth's surface Diamonds can be from 1 to 3 billion years old--more than two-thirds the age of the Earth itself. Diamond is also the hardest substance known to man. In fact, it can only be cut and polished by another diamond. Despite its hardness, however, it is not indestructible. If a diamond is struck at the right angle, it can chip or break. Eye-clean A diamond that has no inclusions visible to the naked eye -- flawless to the naked eye. This is normally true of all diamonds with a grade of about SI-1 or higher on the clarity scale. Facet The polished flat surfaces on a diamond. For example, a round brilliant diamond has 58 fac-ets including the culet. Fair Cut Diamonds cut to less than perfect proportions. They have been cut to maximize the weight of the stone instead of enhancing the brilliance and sacrifice fire and brilliance. The less ex-pensive stones may have good and very good cuts but will not have the same brilliance and fire that people would expect from a diamond. Fire Fire is the colored light that is reflected from inside the diamond. Colored light reflected from within a diamond. As in a prism light en-tering a diamond is divided up into the spec-trum. The better quality diamond with better proportions the better the 'fire' of the diamond. This is called "refraction" or "dispersion" in

the diamond trade. Fluorescence A glow, usually of a bluish color, which emanates from certain diamonds when exposed to ul-traviolet light. Two thirds of all diamonds fluoresce to some degree but how they do so depends very much on the type of ultra violet light they are under. Girdle this is the narrow band around the outer circumference of a diamond. This is where a jewelry setting holds the diamond in a ring. Good Cut Diamonds cut with acceptable, but not perfect, proportions. They generally have very good bril-liance and fire and make excellent jewelry. Ice A colloquial word for diamonds, much favored by Hollywood in movies about gangsters. Ideal Cut Ideal Cut diamonds are usually more expensive than all other cut grades. This is due to three major factors: 1) extra time and skill are required to cut to such precision; 2) they are in great demand, and perhaps most importantly, 3) more of the original rough diamond must be sacri-ficed to achieve ideal proportions. Ideal Cut diamonds are also round diamonds that are perfect-ly proportioned (having depth percentages and table percentages that some people feel produce a "perfect" balance of fire and brilliance). They almost always have the highest grades on polish and symmetry as well, indicating the great care taken in the overall fashioning of the stone. These diamonds have had the finest craftsmanship to maximize the beauty of the diamond. Inclusion An impurity within a diamond, such as a spot or irregularity in the crystal structure of the stone. These can include a cloud, a fracture, another diamond inside the bigger one, liquid, etc. Inclu-sions can either be visible with the naked eye (usually SI-3 clarity and below) or visible only under magnification. Fewer inclusions means a finer clarity grade, increased rarity, and in-creased value. Kimberlite Kimberlite is a mica peridotite and a source of rich deposits of diamonds. The deposits occur-ring at Kimberley, South Africa were the first recognized and the source of the name. The Kim-berly diamonds were originally found in decomposed kimberlite which was colored yellow by limonite, and so was called "yellow ground." Deeper workings encountered less altered rock, undecomposed kimberlite, which miners call "blue ground. Loupe A loupe is a small magnifying glass used to view gemstones. Usually 10x, or ten-power, magni-fication. The FTC requires all diamond grading be done under 10-power magnification; any flaws not detected under this magnification are considered to be non-existent by some dealers.

Make Make describes the quality of the finish and proportions of a diamond. A good make will have proportions that maximize brilliance and fire. A poor make will decrease sparkle and fire due to the loss of light as it travels through the stone. The cutter is responsible for the make of a dia-mond as he is the one that cuts it to achieve the maximum brilliance and fire. Mohs Scale The Mohs scale is a table of relative hardness that ranks a mineral's strength and durability on a scale from 1 to 10, with 1 being talc and 10 being diamond. Developed over 100 years ago by Frederic Mohs. Moissanite Moissanite is silicon carbide and is manufactured in a laboratory. It is virtually indistinguisha-ble from diamonds and it takes a real expert with special equipment to be able to tell the differ-ence. Pavilion This is the bottom half of a diamond, from the lower girdle to the culet tip at the bottom. The pavilion should be neither too deep or too shallow otherwise light will leak out and the diamond will lose fire and brilliance. Peridotite Any of a group of igneous rocks having a granite like texture. Point A measure of diamond weight. One point equals 1/100th of a carat. A diamond that weighs 0.50 carat is said to weigh 50 points. Polish A grade given to the external finish of a stone. The polish grades are from poor to excellent. Good polish is crucial for maximum brilliance of a diamond, but it takes a trained eye to distin-guish between polish grades. Poor Cut Poorly cut diamonds with proportions and finish that make them look relatively lifeless to the eye. Such stones are ok for industry but not for jewelry. Sparkle The 'sparkle' of a diamond is the combination of fire and brilliance. The light that reflects out of a diamond as it moves. Sometimes called "scintillation" by older dealers. Stones A word for diamonds and other precious gems.

Symmetry A diamond should by symmetrical. Symmetry is the grade used to describe the uniformity of the cut of the diamond. This can range from excellent down to poor. The un-symmetrical a diamond is the poorer will be the quality of light through the stone. Table The top or large flat face of the diamond is called the table. It should be in proportion to the rest of the diamond to gain the best fire and brilliance. Tourngat Diamonds cut to fit very strict requirements for depth percentage and table percentage. These outstanding proportions maximize fire and brilliance in the diamond. Also a region of northern Quebec.

Weight the weight of a diamond is measured in car-ats.A carat is .2 grams. A gram of diamond would be a massive 5 carats. Very large in dia-mond terms although the actual diamond is physically small. Wholesale Wholesale prices are listed PER CARAT to show this price difference. For instance, a 1/2-carat round brilliant diamond of G/VS2 quality may sell for $3,600 per carat ($1,800 for the stone), whereas a 1-carat stone of the same quality would likely cost $6,300 per carat ($6,300 for the stone) because it is twice the size and more rare. Zirconia Also known as Cubic Zirconia, this is a sub-stance often used as a substitute to genuine dia-monds. It is a carborundum substance and easi-
