How To Identify If A Diamond Is A Real or A Fake One

Purchasing a diamond may be a difficult experience. We understand: you don’t want to make a costly mistake! However, our clients tell us that it is not the money that is important: it is the sign of your love that you will keep for the rest of your life. That is why it must be perfect. Here are the most frequent diamond purchase blunders we’ve discovered, as well as how to prevent them and choose the ideal diamond for you and the one you love.

1. Take it slow when you plan to purchase a diamond

Buying a diamond is a significant decision, and you should take your time and think about exactly what you want. Do your homework and learn about the four aspects that make up a diamond’s personality, known as the 4 C’s, which are Carat, Cut, Clarity, and Color of Diamond. Learning about diamond characteristics will not make you an expert, but it will help you to debate each stone with your jeweller and better understand how each of the 4 C’s affects the beauty and value of the diamond.

2. Make a budget and stick to it.

This one should be simple, but we frequently see clients struggle with it. According to a  study most of the couples overspent on the diamond. It’s fine to alter your budget if necessary to purchase the ring of your dreams, but once you’ve determined how much you can afford, stick to it.

3. Focus on the Diamond’s cut

Most diamond professionals think that the cut is the most essential of the four C’s. There are four cut grades: Ideal, Excellent, Very Good, and OK. So, what is the significance of the cut? The dimensions of a diamond’s cut impact its ability to transmit light and shine brightly. Cut is sometimes confused with form (round, heart, oval, marquise, and pear), but diamond cut really refers to how effectively a diamond’s facets interact with light.

The more vivid the glitter and fire in the stone, the better the cut. To the untrained eye, one diamond appears to be the same as another, and caret weight or size is frequently the deciding factor. Most individuals, however, prefer a diamond that flashes brightly and passionately, which has little to do with size. A well-cut diamond will be “a cut above the rest,” resulting in a stone that sparkles, fires, and is extremely dazzling.

4. Hoping to find a deal if you search around

Everyone enjoys a good deal, and if we seek hard enough, we will find one. The flip side of the coin is that “you get what you pay for,” and in the case of diamonds, this is a considerably more true depiction of the situation. Most of us expect to get good value for our money, but if an offer appears too good to be true, it generally is. The diamond pricing in the diamond market is strictly controlled by De Beers.

This indicates that the wholesale price is largely set. Retail prices vary depending on the margin the merchant want to earn, but pricing for the same diamond should not change much from one store to the next. Find a reputable jeweller and let them to assist and advise you in obtaining the diamond you desire at a reasonable price.

5. Not all diamond sellers are professionals

There are no qualifications for selling a diamond or any other form of jewellery. Many retail employees are sales professionals rather than product specialists. If you have any questions about the salesperson’s credentials or competence, feel free to inquire, and if required, consult with the business’s owner or goldsmith.  When it comes buying diamonds or any other type of jewellery, trust is crucial.

6. Online purchase of diamonds

Many individuals are comfortable purchasing diamonds online, but it is not for everyone. Online diamond merchants typically have enormous stockpiles of stock, and the stones are frequently not individually inspected by an expert. If an online purchase is being contemplated, it is critical that the buyer understand the 4Cs and how cut impacts the look of the diamond as well as its capacity to dazzle and please the owner.

7. Insist on a certificate

Each diamond should have a certificate issued by a respected organisation such as GIA or EGL that specifies the carat weight, origin (non-conflict), clarity, colour, cut, and any laser engraved number that can identify the diamond as a one-of-a-kind item. When purchasing a diamond, always insist on viewing the diamond’s certificate; only then can you be certain of the stone’s ethical origin. We recommend that you should not buy from a jeweller who is reluctant or unable to show you the certificate before making the transaction.

8. Don’t Get Stuck on Exact Grades

We see it all the time: a customer conducts their homework and determines that a H VS1 is the ideal diamond for them and will not compromise on that grade, even if it means compromising cut, size, or setting. Who will recognise that the diamond is VS1 rather than VS2 when it is set in a ring? Instead of limiting yourself to a single grade, use your money to obtain the greatest diamond possible by evaluating all of the elements. To be honest, the cut is what makes a diamond beautiful: it’s the one thing you should never compromise on.

How to find out if a diamond is a real or a fake one?

Finding out whether or not your diamond is genuine is a fascinating prospect – do you want to know for sure? Most interested citizens seek the advice of a skilled jeweller. But you don’t have to be Sherlock Holmes to know the difference between the real and the fake. All you need is a little light, some water or warm breath, and a jeweler’s loupe.

Test the Mounted Diamonds

1. The Fog Test

Place the stone in front of your lips and fog it up like a mirror. If it remains fogged for more than a few seconds, it’s most likely a fake – a true diamond disperses the heat from your breath instantly and won’t fog up easily. Even if you wait a few seconds between fogging it up and gazing at it, it will clear considerably faster than a fake.

Tip- It might help to place an actual stone next to the suspicious stone and fog both. You can see how the genuine one stays clear while the false one fogs up; if you breathe on phoney diamonds frequently, condensation will begin to form. The false stone will fog up more and more with each puff, but the genuine one will remain pure and clear.

2. Find out more about the setting and the mount

A genuine diamond is unlikely to be placed in a low-cost metal. Inside the setting, stamps showing true gold or platinum (10K, 14K, 18K, 585, 750, 900, 950, PT, Plat) are a positive indicator, but a “C.Z.” stamp indicates that the centre stone is not a genuine diamond. C.Z. is an abbreviation for Cubic Zirconia, a kind of synthetic diamond.

3. Use a jeweler’s loupe to examine the diamond

You can borrow a jeweler’s loupe from a jewellery store. Small naturally occurring flaws termed “inclusions” that may be detected with a loupe are common in mined diamonds. Look for mineral particles or subtle colour shifts. These are both indications that you’re dealing with a genuine, if flawed, diamond.

Tip- Cubic zirconium (which should pass all of the other criteria) is often free of flaws. This is due to the fact that they are developed in sterile conditions rather than being created by accident in the Earth’s laboratory. A jewel that is too flawless is almost always a fake.

Tip- A genuine diamond, on the other hand, may be perfect. Don’t let flaws determine whether or not your diamond is genuine. Other tests should be used first to rule out fakes.

Tip- It is also worth noting that lab-grown diamonds are usually free of flaws since they are created in highly regulated settings. Chemically, physically, and optically similar (and occasionally superior) to naturally occurring diamonds, gem-quality diamonds created in a lab can be chemically, physically, and optically identical (and sometimes superior) to naturally existing diamonds. This potential to outperform the grade of “natural” diamonds has created significant worry among those in the mined diamond industry, who have fought hard to distinguish lab-grown diamonds from “natural diamonds.” Lab-grown diamonds are “real,” but not “natural.”

Checking Unmounted Diamonds

1. Examine the refractivity of the stone

Diamonds strongly bend or refract the light that passes through them, giving them their dazzling look. Because of their lower refractive index, stones such as glass and quartz shine less. The brilliance of a stone is difficult to change, even with an experienced cut, because it is an inherent quality of the stone. You should be able to identify whether a stone is genuine or fake by closely inspecting its refractivity. Here are a few examples:

  • The newspaper method: Place the stone upside down on a piece of newspaper. If you can see distorted black smudges or read print through the stone, it isn’t a diamond. The light would be bent so sharply by a diamond that you wouldn’t be able to see the print. (With a few exceptions: if the diamond’s cut is disproportionate, the print can still be seen through a genuine diamond.)
  • The dot test: On a piece of white paper, draw a small dot with a pen and insert the stone in the middle of the dot. Look at it from the bottom. If your stone isn’t a diamond, you’ll see a circular reflection in it. A genuine diamond will not allow you to see the dot.

2. Monitor the Reflections

The reflections of a genuine diamond are generally in varied hues of grey. Look straight down through the diamond’s top. If you notice rainbow reflections, you’re looking at a low-quality diamond or a fake.

  • Look for Sparkle: A genuine diamond will shine far more than an equivalent-sized chunk of glass or quartz. You might wish to bring a piece of glass or quartz with you as a reference.
  • Sparkle and Reflection are not the same: Don’t mix up glitter and reflection. The brilliance or intensity of the light refracted by the cut of the gem is referred to as sparkle. Reflection is related to the hue of the refracted light. So seek for strong light rather than colourful light.
  • Don’t get confused with Moissanite: Moissanite is a stone with even greater brilliance than a diamond. This gemstone is so close to diamond that even jewellers have difficulty distinguishing between the two. Hold the stone up to your eye to tell the difference if you don’t have any extra equipment. Use a penlight to shine through the stone. The presence of rainbow hues indicates the presence of double refraction. This is a moissanite property, not a diamond property.

3. The Water Method

Place the stone in a glass of water and see if it sinks to the bottom. A genuine diamond will sink due to its great density. A fake one will float at the surface or in the centre of the glass.

4. The Heat Method

Heat the stone and check to see whether it shatters. Warm a suspicious stone with a lighter for 30 seconds before dropping it into a glass of cold water. The fast expansion and contraction will overcome the tensile strength of lesser materials, such as glass or quartz, causing the stone to fracture from within. Nothing can happen because a genuine diamond is so robust.

Professional Testing of Diamond

1. The Heat Probe Test

Diamonds’ tight, evenly-packed crystalline structure allows them to dissipate heat fast, thus genuine diamonds do not heat up readily. Heat probe testing take around 30 seconds and are frequently provided for free. It also does not harm the stone in the manner that other methods of testing do.

Tip-Heat testing is effective for the same reasons that the DIY “shatter” test is effective. Heat probes, on the other hand, assess how long the diamond holds warmth rather than whether it breaks under the strain of fast contraction.

Tip-If you want your diamond properly tested, seek for a trustworthy jeweller in your region online.

2. Request diamond/moissanite testing in combo.

Many jewellers have sophisticated instruments that can tell the difference between a diamond and a moissanite and can swiftly determine whether a stone is a genuine diamond or a simulant.

  • A conventional heat probe test will not be able to distinguish between moissanite and a genuine diamond. Check that the test is being performed using an electrical conductivity tester rather than a thermal tester.
  • Combination testers may be purchased online or at diamond specialty shops if you want to test a large number of gems at home.

3. Microscope Examination

Place the diamond under a microscope, top facet down. With tweezers, gently move the diamond back and forth. If the diamond has a little orange flare along the facets, it might be Cubic Zirconia. It might also mean that Cubic Zirconia was utilised to fix flaws in the diamond. You can get the best view of the diamond under a 1200x power microscope.

4. The Weighing Test

Diamonds may be identified by very slight weight variations, since cubic zirconia weighs roughly 55% more than diamonds of the same shape and size.  To do this comparison, a highly sensitive scale capable of measuring down to the carat or grain level is required. The only way to execute this test correctly is to have a known genuine diamond of about the same size and shape. You won’t be able to tell whether the weight is off unless you have anything to compare it against.

5. The X-Ray Examination

Diamonds have a radiolucent molecular structure, therefore they do not appear in x-ray pictures. Glass, cubic zirconium, and crystals are all somewhat radiopaque, allowing them to be seen clearly on an x-ray.

Tip- If you want to have your diamond x-ray analysed, you must either send it to a professional diamond testing lab or make an arrangement with your local x-ray imaging facility.

Proof of a Real Diamond

1. Locate a trustworthy diamond appraiser in your region

Most diamond merchants employ their own gemologists and appraisers, but many customers prefer to obtain a third-party evaluation from an independent gemologist who specialises in diamond appraisal. If you’re intending to invest in a stone or are interested about a stone you already possess, you’ll want to be sure it’s correctly evaluated.

Tip- An assessment consists of two fundamental steps: identifying and assessing the stone in issue, followed by giving a value. When looking for independent appraisers, seek for someone who has a Graduate Gemologist (GG) degree from a Gemological Institute in your nation and isn’t directly involved in the sale of diamonds.  You may be confident that the science is sound this way.

Tip-When you take your diamond to be appraised, be sure it is appraised by someone who is well-known in your neighbourhood. However, it’s also a good idea to select a jeweller who will assess the stone right in front of you, rather than removing it out of your sight.

2. Ask the appropriate questions

Aside from determining whether or not the stone is genuine, a skilled appraiser can answer a range of questions concerning the quality of your stone to ensure that you are not being taken advantage of. This is especially essential if you already own or inherited a stone. The gemologist should be able to inform you about the following:

  • If the stone is artificial or natural (It should be noted that man-made diamonds are diamonds, but not “natural” diamonds.) For additional information, see the section on identifying man-made diamonds.)
  • Whether or not the stone’s hue has been changed
  • If the stone has received permanent or interim treatment
  • Whether or not a stone corresponds to the grading paperwork given by a retailer

3. Request an appraisal certificate

Whatever tests you select, the best and most reliable method to tell if a diamond is real is to examine the paperwork and consult with a gemologist or appraiser. Certification and grading ensure that your stone has been “proved” to be genuine by specialists. Proof is especially crucial if you’re buying a stone online without seeing it first. Request a certificate.

Tip-The best method to ensure your diamond’s authenticity is to get it verified by an institution such as the Gemological Institute of America, or GIA. If there is a facility near you, you may bring your diamond there, or you can have it taken from the setting by a competent jeweller and shipped to the GIA.

4.Examine your certificate thoroughly; not all certificates are made equal

 The certificate should be issued by a grading authority (e.g., GIA, AGSL, LGP, PGGL) or an independent appraiser who is a member of a professional organisation (such as the American Society of Appraisers) but not by a single store.

Certificates include a wealth of information on your diamond, including carat weight, measurements, proportions, clarity, colour, and cut grade.

Certificates may sometimes include information that you would not anticipate from a jeweller. They are as follows:

  • Fluorescence, or the diamond’s proclivity to emit a mild glow when exposed to UV light.
  • Polish, also known as surface smoothness.
  • Symmetry, or the degree to which opposing aspects perfectly mirror one other.

5. Register your stone

Once you’ve determined that your diamond is genuine, whether through an independent assessment or a grading lab, take it to a lab that can register and fingerprint it. This ensures that have your genuine stone and that no one can swap it out without your knowledge.

Tip- GIA (Gemological Institute of America) diamond, pearl, and coloured stone reports are regarded and accepted as the gold standard for unbiased gemstone quality evaluation all around the globe. The Institute’s laboratory in Mumbai is a cutting-edge facility located near the Bharat Diamond Bourse in the Bandra-Kurla Complex.
