False claims and highly-priced deals: How to spot fraud and keep away from misrepresentation.
There are many elements have an effect on best and price in diamonds. When the average individual is looking at a diamond already set, it’s far very tough, if no longer not possible, to see variations which can dramatically affect price. For this motive, we advocated buying any important diamond un-set up, and mounting it most effective after all the statistics were demonstrated. But, you do not have to be a “gemologist” or worry shopping for earrings. If you follow some simple steps, everybody should buy with self assurance. 鑽石價格
Four key steps to heading off fraud or misrepresentation:
The first step is to shop for from a person accessible and knowledgeable.
Sellers should have the talent to understand for certain what they themselves are shopping for and promoting. This isn’t to say that there are not bargains to be located in flea markets, estate income, and so forth, but you run a better risk whilst purchasing in such locations because of feasible incorrect information , intentional or in any other case. You should weight the hazard as opposed to the potential praise. In addition, earlier than creating a very last buying decision, ask yourself whether or not you may be able to discover the vendor once more if what you bought turns out to be aside from represented. This is similarly actual whilst travelling and thinking about a jewellery buy abroad.
Second, ask the right questions.
Don’t be afraid to ask direct, even pointed questions. The key to getting entire information approximately what you are buying is calling exact questions so that you can be positive you are aware of vital factors affecting exceptional and value.
Third, get the statistics in writing.
Be sure the vendor is willing to put the answers to the questions you ask, and any representations made approximately the gem or jewelry you are considering, in writing. If not, we recommend towards purchasing from this dealer until there may be an unconditional go back coverage which allows merchandise to back within a reasonable time period for a full refund (no longer a shop credit).
Finally, affirm the data with a gemologist appraiser.
It’s mainly important to verify some thing has been put in writing with a expert gemologist appraiser. Some unscrupulous dealers are willing to put something in writing to make the sale, understanding that written assurances or claims about the stone are regularly enough to meet consumers’ doubts. So this ultimate step may be the most vital to make certain you’re making a smart decision.
Types of Misrepresentation
Beware of deals!
Diamonds represented to be higher than they are
Beware of bargains. Most aren’t. When a price appears too precise to be proper, it except the seller would not recognise its genuine price (which reflects badly on the vendor’s expertise).
Scams concerning appraisals prior to sale
Beware of jewelers no inclined to put the statistics in writing, but who provide to permit you to take the stone, to an appraiser inside the community. This may be a rip-off.
One should constantly be cautious of pointers from the seller. While valid jewelers typically understand better than every body else who the best gemologist appraisers are in their groups, and their tips have to be respected, you must nonetheless make sure to check the credentials must be respected, you ought to still make sure to test the credentials yourself to keep away from such scams.
In preferred, you want to shield towards fraud or misrepresentation in one of the following 4 regions:
Color alteration and misgrading
Flaw concealment and misgrading
Certification, alteration and counterfeit certificate
Giving “general weight” of all stones where multiple is worried, instead of the exact weight of the primary stone, is any other form of misrepresentation. This is in strict violation of federal Trade Commission (FTC) rulings. I giving the burden, particularly on any show card, descriptive tag, or other form of advertising for a specific piece of jewelry, the burden of the main stone or stones should be indicated as well as the total weight of the all the stones.
Enhancing color artificially
Touching the culet, or facet of a barely yellow stone with a coating of pink ink, which includes found in a indelible pencil, neutralizes the yellow, generating a extra white looking stone. This can be without problems detected by way of washing the stone in alcohol or water. If you have ay questions on the coloration, tactfully request that the stone be washed (in front of you) for better examination for higher examination. A respectable jeweler ought to don’t have any objection to this request.
Improving the shade via utilising a sputtering method (also referred to as “portray” the diamond). This includes sputtering a totally thin coating of a unique substance over the stone or a part of the stone, generally the again, in which it will be tougher to discover while installed. The girdle region can also be painted with the substance and create the same impact. The substance, like indelible pencil, additionally neutralize the yellow and thereby improves the coloration through as lots as seven coloration grades, however not like indelible ink, the substance will not wash off. It can be eliminated in approaches: through rubbing the stone in a timely fashion and firmly with a purifier, or by boiling the stone carefully in sulfuric acid. If the stone is already set up and is lined on the returned, the use of cleaner isn’t possible. The sulfuric acid approach is the handiest way. But please word, using sulfuric acid can be extraordinarily risky, and must be carried out best via an skilled character.
This approach isn’t regularly used, however stones handled on this way do seem regularly enough to be worth mentioning.
Coating the diamond with chemical substances and baking it in a small lab type oven. This technique also tends to neutralize some of the yellow, thereby producing a higher coloration grade. This coating could be removed ultimately by repeated warm ultrasonic cleanings, in an effort to step by step erode the coating. A more speedy elimination may be performed with the aid of the greater risky method of boiling in sulfuric acid.
Radiation treatment. Exposing off shade diamonds which include yellowish or brownish tinted stones (and additionally badly fallacious stones in which the failings would be less significant in opposition to a coloured heritage) to positive kinds of radiation can bring about the manufacturing of fancy colored stones. This treatment produces wealthy yellows, vegetables, and blues, and greatly complements salability due to the fact these hues are very desirable. In and of itself, radiation isn’t fraud; it could make a elaborate coloration diamond inexpensive to a person in any other case not able to buy one. But once more, just make sure that the stone is well represented and what you are shopping for, and which you are becoming it on the proper fee, which must be much lower than that of the natural fancy.
Treated diamonds have to be represented as “handled diamonds” and ought to be priced accordingly. Whether the color is natural or treated may be furnished through a gem testing laboratory. Not all gemologists, but, are competent with spectroscopic procedures, and a few fancy colour diamond require examination with very sophisticated system not to be had to most labs. Most herbal fancy coloured diamonds offered by using jewelers inside the United States are observed by means of a GIA diamond file.
Clarity enhancement and flaw concealment
Be particularly alert to the opportunity that clarity can be improved. The most frequently used techniques are lasering inclusions and filling the fractures. In both cases, dark inclusions or cracks which might commonly be seen, in some cases, very visible, are concealed, or grow to be an awful lot much less sizeable. Be sure to ask whether or no longer the stone has been lasered or crammed. As lengthy as you realize, and pay the right charge, a clarity more advantageous diamond can be an appealing preference.
Where feasible, flaws are hid with the aid of their settings. The excellent stone setter will try to set a stone in the sort of manner that the putting will assist to conceal any seen imperfections. For this reason flaws near or at the girdle will downgrade a stone much less than those determined inside the center of the stone; since most settings cover all or part of the girdle, they’re simply much less visible here. Indeed, a setting could make a flaw “invisible.”
There is not anything fraudulent in such makes use of of settings as long as the stone is well represented. The most effective risk is that now not most effective the patron however also the jeweler may not have the imperfection concealment through the setting.
Can concealment affect price? In most diamonds apart from FL or IF, the presence of a minor flaw concealed beneath a prong will not have an effect on the fee considerably. However, given the difference in price between diamonds graded FL or IF and VVS1, a minor blemish or inclusion hidden with the aid of the putting which would possibly bring about a VVS1 diamond being graded FL should have a enormous have an effect on on cost, in particular if the stone has notably exceptional coloration. For this purpose diamonds need to be considered UN-mounted.
Certification of diamonds
Most diamonds weighting one carat or extra are cautiously evaluated prior to being set by way of a reputable laboratory such as the GIA or the AGL, and are issued a diamond grading document. That report each certifies the diamond as genuine and describes it, providing vital facts as shade grade, flaw grade, weight reducing and proportioning, and so on. If you’re considering the purchasing of a totally high-quality diamond weighing one carat or extra and it is not observed via this kind of report, we would strongly advise which you or the vendor have the stone evaluated with the aid of the GIA or another respected laboratory prior to purchase. You should accomplish that despite the fact that it approach having a stone this is already set removed from the setting and reset. Given the widespread distinction in cost that may result from a grading blunders in the rarer grades, we believes this procedure is really worth the inconvenience and expense.
Unfortunately, the self belief of the public in diamonds accompanied by way of the certificates has given rise to the exercise of changing and counterfeiting them. While you could be enormously positive that “certificated” diamonds offered by using respectable, mounted earrings firms are what they claim to be, there are some suppliers and sellers who are seizing possibilities to prey at the unsuspecting.
Sometimes information is modified on an in any other case valid certificate; for instance, the flaw or colour grade may be altered. If you have any question regarding facts at the certificate, a smartphone call to the lab (or its net site) giving them the certificate range and date will allow you to verify the facts on the certificate.
Producing a certificates from a nonexistent lab is an an increasing number of commonplace hassle. Stones observed through fancy “certificates” from superb sounding labs that do not exist are acting an increasing number of often. If the certificates is not from one of the diagnosed labs, it must be cautiously checked. If the lab seems legitimate, name to verify the records at the certificate, and if all appears so as, you can in all likelihood rest easily. Otherwise, you can want to have the statistics confirmed by using another gemologist or diagnosed lab.
Switching the stone described on a file
In some cases the report is bona fide but the stone has been switched. To defend each the purchaser and the lab, some labs are taking advantage of innovative strategies to make sure against switching. For instance, a service called gem-print utilizes laser generation to show a diamond’s specific pattern of reflection after which facts it photographically. The end result is an digital “fingerprint” of the diamond which may be used for identity purposes. In addition, the GIA can now genuinely inscribe its file range, that’s seen most effective beneath magnification, at once onto the diamond itself, along the girdle. By so doing, on can very without problems make sure a specific diamond matches a particular certificates definitely via matching the numbers.
In the absence of the sort of mark, one clue to a switched diamond might be provided by evaluating the carat weight and dimensions given on the report. If the measurements and carat weight healthy precisely, the chance is slender that a diamond has been switched, provided the document has no longer been altered.
If the stone has been set up, it could be tough to get unique measurements to evaluate.
Always make certain, for both your protection and the jeweler’s, that the jeweler writes down at the invoice of the sale or memo all of the stone’s dimensions as satisfactory as can be determined: diameter or length and width, depth, and weight. This is to assist ensure which you are not accused of switching the diamond after leaving the premises in the occasion you should return it.
Is it a diamond or a diamond imposter?
How can you inform if a stone is truely a diamond? Unless, you are an expert, or consult one, you can not make sure about the identity of a stone. Nevertheless, there are some easy tests you could perform with the intention to display up most diamond imposters quite quickly. Here are a few matters to search for:
Is newsprint readable or observable through the stone?
If the is a spherical modern-day reduce stone and is free or hooked up in such a way as to can help you area it desk down over a few small newsprint, take a look at whether or not you can see or study any portion of the lettering. If so, it is not a diamond. Refraction of mild within a proper diamond is such you will no longer be capable of see any of the letters inside the newsprint.
Is the stone open or closed?
Diamonds are seldom glued in. Rhinestones often are.
Is the returned open or closed?
If the stone is a properly set diamond, the back of the setting will normally be open, permitting you to simply see a part of the pavilion. Some very small rose cut or unmarried reduce diamonds, as seen in some precise rings, Any be established with a closed back. Otherwise, if a hoop has a closed again, it might be rhinestone, in which case the back is regularly closed in order to hide the foil that has been applied to the returned of the stone.
How many facets are visible on the pinnacle?
In cheaper glass imitations best 9 top facets are usually seen, instead of 33 visible pinnacle facets in a diamond or correct simulation. Single cut or Swiss reduce diamonds can even show simplest nine facets on the pinnacle, but they’ll be set in open lower back mountings, whereas reasonably-priced glass imitations are generally set in closed returned mountings.
Does the girdle of the stone seem like frosted?
The girdles of maximum diamonds are unpolished, with a ground glass like seem that shows “frostiness.” The re are a few diamond imitations that also have a frosted appearance, however of all of these, a diamond has the whitest frostiness, like clean, dry, round glass. On the alternative hand, some diamonds do have polished or faceted girdles, and consequently no frostiness can be present. You can expand an eye for this by means of asking a reliable jeweler to point out the differences among a cultured girdle, an unpolished girdle, and a faceted girdle.
Is the reduce symmetrical?
Since diamond is so precious and symmetry so crucial to its overall look and desirability, the symmetry of faceting on a diamond will be very cautiously finished, while in diamond simulations the symmetry of the facets may be sloppy. For instance, the eight kite shaped facets (occasionally called bezel facets) will often be lacking one or more factors at the aspect, or on the top or bottom, showing a small immediately side in place of a point. This sloppy faceting may be an critical indication that the stone in question is not a diamond, since it indicated that a cutter did not take proper care. It ought to be noted that some poorer grade or antique cut diamonds may display sloppiness
Are the crown and pavilion of the stone properly aligned?
While now and again a diamond can also display partial misalignment, imitations are often and often badly misaligned.
Are the side or faces scratched, chipped, or worn?
Diamond imitations encompass some stones which are very smooth and/or brittle, which include zircon, GGG (a man made simulation), Fabulite (a man made diamond simulation additionally recognize as Wellington Diamond), and glass. Due their lack of hardness and, inside the case of zircon, possible brittleness, those imitations will show put on without difficulty, and possible frequently come across scratches or chips at the aspect edges or faces. The edges are truly greater vulnerable and scratches or chips can be more easily seen there, so check the edges first. The check then flat faces for scratches. Check both the place what might be maximum exposed and areas across the prongs, where a setter may by accident have scratched the stone while placing it.
Zircon, a stone observed in nature that is regularly confused with cubic zirconia (CZ), a man made imitation, is quite hard however very brittle, so it’ll nearly usually display chipping at the rims of the aspects if the stone has been worn in rings for a year or more.
Some diamond look-alikes, however, are greater long lasting and immune to substantive put on. These include colorless artificial spinel, colorless artificial sapphire, colorless quartz, YAG (guy made), and CZ. While these may additionally scratch or chip over time with ordinary wear and day by day abuse, scratches or chips are as severa, and may be much less major.
Does the stone, loose or hooked up, exhibit fluorescence underneath ultraviolet light?
This is not something simply carried out by an amateur, nor understandable to the average man or woman because of numerous variables and medical complexities. If, after the above exams, you continue to have doubt, take the stone to qualified gemologist with lab centers and ask him to perceive the stone. If it’s miles a diamond, have him note the character of the stone’s fluorescence, as it can show a valuable device for identity if ever wanted.
An vital word about cubic zirconia
Cubic zirconia (CZ) is the nice diamond simulation made to date, and even some jewelers have unsuitable these stones for diamonds.
CZ is almost as super as diamond, has even greater fire (which masks its lesser brilliance), and is quite hard, giving it suitable sturdiness and put on-capability. CZ is likewise being produced in fancy hues; pink, inexperienced, and yellow, and can provide a nice diamond “alternative” as a way to offset or get dressed up colored stones in jewelry if diamond aren’t low-cost.
How can you tell if you have a CZ?
Some of the exams already discussed may additionally help you stumble on a CZ. The following might also remove any remaining doubt.
If it’s miles a loose stone, have it weighted.
A loose stone can be weighted on a scale, which maximum jewelers have handy, and you may decide how plenty it ought to weigh if it’s far truely a diamond. If the weight is tons extra than the diamond weight need to be, based totally on its unfold, then it is not a diamond. A CZ is approximately 75% heavier than a diamond of the equal unfold. For example, a CZ that seems like a 1 carat diamond size-sensible will weigh 1-3/4 carats; a CZ that looks like a1/four carat diamond in terms of size will weight about forty/100 carat.
Look on the girdle.
If the girdle is frosted, a subdued whiteness corresponding to barely wet or oiled frosted glass will indicate CZ. Looking at girdles to distinguish among the advent of frosted CZ and frosted diamond girdles requires vast revel in.
Test the stone with a carbide scriber.
CZ can be scratched with a satisfactory-point carbide scriber, also to be had at maximum rings deliver stores. If the scriber is forcibly driven perpendicularly to any of the aspects (the table being the perfect) and then drawn across this flat surface, you’ll scratch it. You can’t scratch a diamond besides with another diamond. But be sensible and considerate. Do now not heedlessly scratch merchandise that does not belong to you; particularly if the jeweler or seller doesn’t constitute the stone as a diamond.
Examine the stone, loose or established, for fluorescence.
Both CZ and diamond fluoresce, however the colours and intensities might be special.
Use an digital diamond tester.
These are pocket size diamond testers so that it will tell you what you whether or not or not you have got a diamond. Most might not inform you what you’ve got if it’s not diamond, however handiest affirm whether or now not it’s miles diamond.
After those tests, when you have some questions, take the stone to a qualified gemologist with lab centers for high-quality identity.
Comparing diamond expenses
All too often people look for easy answers to complicated troubles. Many would really like to have a easy list of diamond grades and corresponding charges, through size. Unfortunately, market situations are continuously converting, and greater crucial good sized differences in fine not conveniently discernible to any however the professional. Therefore, it isn’t always viable to provide a easy solution to this complicated query.
