How to Tell if a Diamond is Real

Diamonds are the ultimate symbol of luxury and a popular choice for embellishing significant jewelry pieces such as diamond engagement rings, as well as essential items like diamond earrings and diamond bracelets. Valued as the number one gem on the Mohs hardness scale, their formidable durability makes them a reliable choice for those looking to invest in timeless beauty. Diamonds are also among the top most expensive gemstones globally, which might lead you to wonder how to determine if a diamond is real.

If you are certain you are seeking a natural diamond, also referred to as an authentic or real diamond, the first step in your research should be to visit a trusted jewelry store such as Mumit’s online shop

Specialising in this type of gemstones, their creations are never set with lab diamonds. You may have noticed that the current market is rife with confusing terms used to refer to lower quality products and sell them as natural diamonds. 

For this reason, we strongly advise refining your search to focus exclusively on expert jewelers who explicitly state that they only deal with natural diamonds.

Once the correct terminology is clear, we will delve into the more technical aspects with a detailed guide on how to recognise a real diamond. Would you like to become a true expert? We will let you in on all the secrets.

Visit Accredited Jewelers

If you are considering the best way to ensure that the diamond jewelry you purchase is authentic, our first and most important piece of advice is to visit a renowned jeweler that offers authenticity guarantees. This way, you eliminate the risk of buying a fake diamond, thus ensuring the real value of your investment. As mentioned at the beginning of the article, it is crucial to visit an establishment that clearly shares the origin of its diamonds, allowing you to choose products from jewelers that work with natural diamonds only and have adopted the Kimberley Process.

Another crucial document, especially when purchasing significant pieces such as gold diamond engagement rings, is a certificate from the prestigious GIA laboratory. At Mumit, all diamonds of 0.30 carats or more include this report, ensuring you are acquiring a natural and high-quality product.

For instance, if you are looking for diamond rings for women and wonder how to recognise a diamond in a ring, we recommend examining Mumit’s iconic Ella 0.80 ct Solitaire Diamond Ring in 18k White Gold. Its spectacular central diamond of 0.50 carats comes with a GIA technical evaluation and a unique code also discreetly and imperceptibly laser-engraved on the girdle of the diamond. This way, you can always identify it.

Tests You Can Perform on Your Own

If you have diamond jewelry of dubious origin and would like to know the tests you can perform on your own to determine if they are natural or fake, here are some options you can try from the comfort of your home. It might have crossed your mind to hit the stone and see if it shatters, but if you are looking for safer and more reliable alternatives, keep reading.

Check the Setting and Mount

A simple way to check the quality of the jewel is to look for metal marking, that is, to check if it is engraved with the jewelry store’s seal and the quality of the gold used. If you see a 750 engraved on the back, this means that the gold is 18 karats, and it is a good indication that it is a piece of fine jewelry. It is uncommon to set natural diamonds in metals of lower quality than mentioned, so although it is not a definitive guarantee, this simple method can provide some interesting information.

Fog Test

This test involves holding the diamond near your mouth and exhaling as if you wanted to fog up a glass. If it defogs quickly, it is likely a real diamond. The reason is that heat disperses efficiently in natural diamonds.

Water Test

If you want to continue experimenting, we suggest you fill a glass with water halfway and submerge the diamond. If it floats, it is fake. Real diamonds sink due to the high density of this gemstone.

Inspect a Diamond with a Loupe

You can also observe it under a magnifying glass. If you can see small inclusions or imperfections, it is likely real, as these occur spontaneously during the diamond formation process.

Test a Diamond at Home Using Refractivity

This test is somewhat more complex because it requires the use of a refractometer. If you have access to this gadget, you can test a diamond at home using reflectivity and refractivity. Refractometers measure the way diamonds divert light. A simpler way to measure these parameters is to place the diamond on a newspaper. If you are able to read the text underneath the precious stone in question, it is very likely to be fake.

UV Light Test

The last home verification consists of placing the diamond under ultraviolet light. If you can perceive a certain degree of fluorescence, it is likely a natural diamond, as this is a common feature in many of them.

These tests can be particularly useful for solitaire-style diamond jewelry like Mumit’s Jolie Diamond Earrings in 18k White Gold. With a minimalist design, the beauty of the natural diamond takes centre stage in this timeless jewel.

As we have mentioned, Mumit only works with natural diamonds, so although the carat weight of the diamond is less than 0.30, as is the case with these earrings of 0.20 carats each, and does not include a GIA certificate, you can be sure that they are natural diamonds that have been carefully selected by their experts. You will also find the Mumit seal and the 750 symbol of 18 karat gold engraved on the back.

Professional Verification Process

Lastly, if you still have doubts, it is always possible to go to a certified gemologist or a professional appraiser. These experts will be able to use advanced techniques that are not available at home. They are also qualified to detect certain aspects that are not perceptible to the untrained eye. Once evaluated, they will confirm the authenticity of the diamond in question, its quality, and its market value.

We want to leave you with one last example of a wonderful diamond jewel that you will not have to take to any appraiser: Mumit’s Rosette 0.50 ct Solitaire Diamond Necklace in 18k White Gold. Delicate and dazzling in equal measure, it is a testament to the timeless beauty of natural diamonds.

Whether you are looking for long diamond necklaces or trendy chokers, we are sure you will enjoy admiring the varied selection of layering necklaces from the brand.

We can conclude that there are several ways to know if a diamond is real. While the tests you can perform by yourself contribute to a correct evaluation of the diamond to some extent, you can only be truly sure that you have acquired an authentic diamond if you have bought it from a trusted jeweler or if it is evaluated by an expert. In this way, you will have absolute certainty that you have invested in a natural diamond.
