False claims and dear bargains: The best way to spot fraud and keep away from misrepresentation.

There are a lot of elements have an effect on high quality and worth in diamonds. When the common particular person is a diamond already set, it is extremely tough, if not unattainable, to see variations that may dramatically have an effect on value. Because of this, we really useful shopping for any essential diamond un-mounted, and mounting it solely after all of the info have been verified. However, you do not have to be a “gemologist” or worry shopping for jewellery. When you comply with a number of easy steps, anybody can purchase with confidence.

Step one is to purchase from somebody accessible and educated.

Sellers ought to have the talent to know for positive what they themselves are shopping for and promoting. This isn’t to say that there should not bargains to be present in flea markets, property gross sales, and so forth, however you run a better danger when buying in such locations due to potential misinformation , intentional or in any other case. You could weight the chance versus the potential reward. As well as, earlier than making a last buying choice, ask your self whether or not or not it is possible for you to to search out the vendor once more if what you acquire seems to be apart from represented. That is equally true when touring and contemplating a jewellery buy overseas.

Second, ask the precise questions.

Do not be afraid to ask direct, even pointed questions. The important thing to getting full details about what you might be shopping for is asking good questions so that you could be positive you might be conscious of essential elements affecting high quality and worth.

Third, get the info in writing.

Make sure the vendor is prepared to place the solutions to the questions you ask, and any representations made concerning the gem or jewellery you might be contemplating, in writing. If not, we suggest in opposition to buying from this vendor until there may be an unconditional return coverage which permits merchandise to returned inside an inexpensive time frame for a full refund (not a retailer credit score).

Lastly, confirm the info with a gemologist appraiser.

It is particularly essential to confirm no matter has been put in writing with an expert gemologist appraiser. Some unscrupulous sellers are prepared to place something in writing to make the sale, figuring out that written assurances or claims concerning the stone are sometimes enough to fulfill patrons’ doubts. So this final step could also be a very powerful to make sure you make a sensible choice.

Kinds of Misrepresentation

Watch out for bargains!

Diamonds represented to be higher than they’re

Watch out for bargains. Most should not. When a value appears too good to be true, it until the vendor would not know its true worth (which displays badly on the vendor’s experience).

Scams involving value determinations previous to sale

Watch out for jewelers no prepared to place the info in writing, however who supply to allow you to take the stone, to an appraiser within the neighborhood. This can be a rip-off.

One should at all times watch out of suggestions from the vendor. Whereas authentic jewelers often know higher than anybody else who the very best gemologist appraisers are of their communities, and their suggestions ought to be revered, you should nonetheless make sure to examine the credentials ought to be revered, you should nonetheless make sure to examine the credentials your self to keep away from such scams.

Normally, it’s essential guard in opposition to fraud or misrepresentation in one of many following 4 areas:

Weight misrepresentation

Colour alteration and misgrading

Flaw concealment and misgrading

Certification, alteration and counterfeit certificates
Weight

Giving “complete weight” of all stones the place a couple of is concerned, somewhat than the precise weight of the principle stone, is one other type of misrepresentation. That is in strict violation of federal Commerce Fee (FTC) rulings. I giving the burden, notably on any show card, descriptive tag, or different kind of promoting for a specific piece of bijou, the burden of the principle stone or stones ought to be indicated in addition to the whole weight of the all of the stones.

Colour

Enhancing coloration artificially

Touching the culet, or aspect of a barely yellow stone with a coating of purple ink, similar to present in a indelible pencil, neutralizes the yellow, producing a extra white trying stone. This may be simply detected by washing the stone in alcohol or water. You probably have ay questions concerning the coloration, tactfully request that the stone be washed (in entrance of you) for higher examination for higher examination. A good jeweler shouldn’t have any objection to this request.

Enhancing the colour by using a sputtering method (additionally known as “portray” the diamond). This entails sputtering a really skinny coating of a particular substance over the stone or a part of the stone, often the again, the place will probably be tougher to detect when mounted. The girdle space can be painted with the substance and create the identical impact. The substance, like indelible pencil, additionally neutralize the yellow and thereby improves the colour by as a lot as seven coloration grades, however in contrast to indelible ink, the substance won’t wash off. It may be eliminated in two methods: by rubbing the stone briskly and firmly with a cleanser, or by boiling the stone rigorously in sulfuric acid. If the stone is already mounted and is coated on the again, utilizing cleanser will not be possible. The sulfuric acid methodology is the one means. However please observe, utilizing sulfuric acid could be extraordinarily harmful, and should be achieved solely by an skilled particular person.

This system will not be steadily used, however stones handled on this method do seem usually sufficient to be price mentioning.

Coating the diamond with chemical compounds and baking it in a small lab kind oven. This system additionally tends to neutralize among the yellow, thereby producing a greater coloration grade. This coating will probably be eliminated ultimately by repeated scorching ultrasonic cleanings, which is able to progressively erode the coating. A extra speedy elimination could be achieved by the extra harmful methodology of boiling in sulfuric acid.

Radiation remedy. Exposing off coloration diamonds similar to yellowish or brownish tinted stones (and likewise badly flawed stones during which the issues can be much less noticeable in opposition to a coloured background) to sure varieties of radiation may end up in the manufacturing of fancy coloured stones. This remedy produces wealthy yellows, greens, and blues, and drastically enhances salability as a result of these colours are very fascinating. In and of itself, radiation will not be fraud; it could make a flowery coloration diamond reasonably priced to somebody in any other case unable to buy one. However once more, simply ensure that the stone is correctly represented and you understand what you might be shopping for, and that you’re getting it on the proper value, which ought to be a lot decrease than that of the pure fancy.

Handled diamonds should be represented as “handled diamonds” and ought to be priced accordingly. Whether or not the colour is pure or handled could be offered by a gem testing laboratory. Not all gemologists, nevertheless, are competent with spectroscopic procedures, and a few fancy coloration diamond require examination with very subtle gear not obtainable to most labs. Most pure fancy coloured diamonds bought by jewelers in the US are accompanied by a GIA diamond report.

Readability enhancement and flaw concealment

Readability enhancement

Be particularly alert to the chance that readability could also be enhanced. The 2 most steadily used strategies are lasering inclusions and filling the fractures. In each instances, darkish inclusions or cracks which could usually be seen, in some instances, very seen, are hid, or develop into a lot much less noticeable. You should definitely ask whether or not or not the stone has been lasered or crammed. So long as you understand, and pay the precise value, a readability enhanced diamond could also be a beautiful alternative.

Flaw concealment

The place potential, flaws are hid by their settings. The nice stone setter will attempt to set a stone in such a way that the setting will assist to hide any seen imperfections. Because of this flaws close to or on the girdle will downgrade a stone lower than these discovered within the heart of the stone; since most settings cowl all or a part of the girdle, they’re merely much less seen right here. Certainly, a setting could make a flaw “invisible.”
There’s nothing fraudulent in such makes use of of settings so long as the stone is correctly represented. The one hazard is that not solely the shopper but in addition the jeweler could not have the imperfection concealment by the setting.

Can concealment have an effect on worth? In most diamonds apart from FL or IF, the presence of a minor flaw hid underneath a prong won’t have an effect on the value considerably. Nonetheless, given the distinction in value between diamonds graded FL or IF and VVS1, a minor blemish or inclusion hidden by the setting which could lead to a VVS1 diamond being graded FL may have a big have an effect on on worth, particularly if the stone has exceptionally effective coloration. Because of this diamonds ought to be considered UN-mounted.

Certification of diamonds

Most diamonds weighting one carat or extra are rigorously evaluated previous to being set by a revered laboratory such because the GIA or the AGL, and are issued a diamond grading report. That report each certifies the diamond as real and describes it, offering essential info as coloration grade, flaw grade, weight chopping and proportioning, and so forth. If you’re contemplating the buying of a really effective diamond weighing one carat or extra and it isn’t accompanied by such a report, we might strongly suggest that you just or the vendor have the stone evaluated by the GIA or one other revered laboratory prior to buy. It is best to accomplish that even when it means having a stone that’s already set faraway from the setting and reset. Given the numerous distinction in value that may outcome from a grading error within the rarer grades, we believes this process is definitely worth the inconvenience and expense.

Sadly, the boldness of the general public in diamonds accompanied by the certificates has given rise to the observe of altering and counterfeiting them. When you could be comparatively positive that “certificated” diamonds bought by respected, established jewellery corporations are what they declare to be, there are some suppliers and sellers who’re seizing alternatives to prey on the unsuspecting.

Altering certificates

Generally info is modified on an in any other case legitimate certificates; for instance, the flaw or coloration grade could also be altered. You probably have any query relating to info on the certificates, a cellphone name to the lab (or its website) giving them the certificates quantity and date will allow you to confirm the data on the certificates.

Counterfeit certificates

Producing a certificates from a nonexistent lab is an more and more frequent downside. Stones accompanied by fancy “certificates” from spectacular sounding labs that do not exist are showing an increasing number of steadily. If the certificates will not be from one of many acknowledged labs, it ought to be rigorously checked. If the lab appears authentic, name to confirm the data on the certificates, and if all appears so as, you may in all probability relaxation comfortably. In any other case, it’s possible you’ll must have the info verified by one other gemologist or acknowledged lab.

Switching the stone described on a report

In some instances the report is bona fide however the stone has been switched. To guard each the patron and the lab, some labs are profiting from ingenious strategies to make sure in opposition to switching. For instance, a service known as gem-print makes use of laser know-how to show a diamond’s distinctive sample of reflection after which information it photographically. The result’s an digital “fingerprint” of the diamond which can be utilized for identification functions. As well as, the GIA can now really inscribe its report quantity, which is seen solely underneath magnification, immediately onto the diamond itself, alongside the girdle. By so doing, on can very simply make sure a particular diamond matches a particular certificates just by matching the numbers.

Within the absence of such a mark, one clue to a switched diamond could be offered by evaluating the carat weight and dimensions given on the report. If the measurements and carat weight match precisely, the likelihood is slim diamond has been switched, offered the report has not been altered.
If the stone has been mounted, it could be tough to get exact measurements to match.

At all times ensure that, for each your safety and the jeweler’s, that the jeweler writes down on the invoice of the sale or memo all of the stone’s dimensions as finest as could be decided: diameter or size and width, depth, and weight. That is to assist guarantee that you’re not accused of switching the diamond after leaving the premises within the occasion you should return it.

Is it a diamond or a diamond imposter?

How will you inform if a stone is known as a diamond? Except, you might be an skilled, or seek the advice of one, you cannot make sure concerning the identification of a stone. Nonetheless, there are a number of easy checks you may carry out that may present up most diamond imposters fairly shortly. Right here are some things to search for:

Is newsprint readable or observable by the stone?
If the is a spherical trendy lower stone and is free or mounted in such a means as to let you place it desk down over some small newsprint, examine whether or not you may see or learn any portion of the lettering. In that case, it isn’t a diamond. Refraction of sunshine inside a real diamond is such you will be unable to see any of the letters within the newsprint.
Is the stone open or closed?
Diamonds are seldom glued in. Rhinestones usually are.
Is the again open or closed?
If the stone is a correctly set diamond, the again of the setting will often be open, permitting you to readily see a portion of the pavilion. Some very small rose lower or single lower diamonds, as seen in some distinctive jewellery, Any be mounted with a closed again. In any other case, if a hoop has a closed again, it’s in all probability rhinestone, during which case the again is usually closed in an effort to conceal the foil that has been utilized to the again of the stone.
What number of sides are seen on the highest?
In cheaper glass imitations solely 9 high sides are often seen, versus 33 seen high sides in a diamond or good simulation. Single lower or Swiss lower diamonds will even present solely 9 sides on the highest, however they are going to be set in open again mountings, whereas low-cost glass imitations are often set in closed again mountings.
Does the girdle of the stone look like frosted?
The girdles of most diamonds are unpolished, with a floor glass like seem that means “frostiness.” The re are some diamond imitations that even have a frosted look, however of all of those, a diamond has the whitest frostiness, like clear, dry, spherical glass. However, some diamonds do have polished or faceted girdles, and thus no frostiness will probably be current. You possibly can develop a watch for this by asking a dependable jeweler to level out the variations between a sophisticated girdle, an unpolished girdle, and a faceted girdle.
Is the lower symmetrical?
Since diamond is so helpful and symmetry so essential to its total look and desirability, the symmetry of faceting on a diamond will probably be very rigorously executed, whereas in diamond simulations the symmetry of the sides could also be sloppy. For instance, the eight kite formed sides (typically known as bezel sides) will usually be lacking a number of factors on the aspect, or on the highest or backside, exhibiting a small straight edge somewhat than some extent. This sloppy faceting could be an essential indication that the stone in query will not be a diamond, because it indicated cutter didn’t take correct care. It ought to be famous that some poorer grade or outdated lower diamonds might also present sloppiness
Are the crown and pavilion of the stone correctly aligned?
Whereas often a diamond could present partial misalignment, imitations are steadily and infrequently badly misaligned.
Are the aspect or faces scratched, chipped, or worn?
Diamond imitations embrace some stones which might be very tender and/or brittle, similar to zircon, GGG (a person made simulation), Fabulite (a person made diamond simulation additionally know as Wellington Diamond), and glass. Due their lack of hardness and, within the case of zircon, potential brittleness, these imitations will present put on simply, and one can usually detect scratches or chips on the aspect edges or faces. The perimeters are considerably extra weak and scratches or chips could also be extra simply seen there, so examine the sides first. The examine then flat faces for scratches. Verify each the world what can be most uncovered and areas across the prongs, the place a setter may by accident have scratched the stone whereas setting it.
Zircon, a stone present in nature that’s usually confused with cubic zirconia (CZ), a person made imitation, is comparatively exhausting however very brittle, so it is going to virtually at all times present chipping on the edges of the sides if the stone has been worn in jewellery for a 12 months or extra.
Some diamond look-alikes, nevertheless, are extra sturdy and proof against noticeable put on. These embrace colorless artificial spinel, colorless artificial sapphire, colorless quartz, YAG (artificial), and CZ. Whereas these could scratch or chip over time with common put on and day by day abuse, scratches or chips are as quite a few, and will probably be much less noticeable.
Does the stone, free or mounted, exhibit fluorescence underneath ultraviolet mild?
This isn’t one thing readily achieved by an beginner, nor understandable to the common particular person due to quite a few variables and scientific complexities. If, after the above checks, you continue to have doubt, take the stone to certified gemologist with lab amenities and ask him to establish the stone. If it’s a diamond, have him observe the character of the stone’s fluorescence, as it may possibly show a helpful software for identification if ever wanted.
An essential phrase about cubic zirconia

Cubic zirconia (CZ) is the very best diamond simulation made thus far, and even some jewelers have mistaken these stones for diamonds.
CZ is sort of as good as diamond, has even higher fireplace (which masks its lesser brilliance), and is comparatively exhausting, giving it good sturdiness and wear-ability. CZ can be being produced in fancy colours; purple, inexperienced, and yellow, and may present a pleasant diamond “various” as a way to offset or costume up coloured stones in jewellery if diamond should not reasonably priced.

How will you inform in case you have a CZ?

A number of the checks already mentioned could enable you to detect a CZ. The next could eradicate any remaining doubt.

If it’s a free stone, have it weighted.

A free stone could be weighted on a scale, which most jewelers have helpful, and you may decide how a lot it ought to weigh whether it is really a diamond. If the burden is far higher than the diamond weight ought to be, primarily based on its unfold, then it isn’t a diamond. A CZ is roughly 75% heavier than a diamond of the identical unfold. For instance, a CZ that appears like a 1 carat diamond size-wise will weigh 1-Three/four carats; a CZ that appears like a1/four carat diamond when it comes to measurement will weight roughly 40/100 carat.
Take a look at the girdle.

If the girdle is frosted, a subdued whiteness resembling barely moist or oiled frosted glass will point out CZ. Taking a look at girdles to distinguish between the looks of frosted CZ and frosted diamond girdles requires appreciable expertise.

Check the stone with a carbide scriber.

CZ could be scratched with a fine-point carbide scriber, additionally obtainable at most jewellery provide shops. If the scriber is forcibly pushed perpendicularly to any of the sides (the desk being the best) after which drawn throughout this flat floor, you’ll scratch it. You cannot scratch a diamond besides with one other diamond. However be smart and thoughtful. Don’t heedlessly scratch merchandise that does not belong to you; notably if the jeweler or vendor would not characterize the stone as a diamond.
Look at the stone, free or mounted, for fluorescence.
Each CZ and diamond fluoresce, however the colours and intensities will probably be totally different.
