We have listed below the questions that are most posed to us, hoping to answer them with as much clarity as possible and by giving you some techniques to help you distinguish between true and false without being a diamond dealer or a gemologist expert in precious stones. For more information, do not hesitate to contact us directly by phone or e-mail.

What is the best guarantee that my diamond is a real one?

The best proof is the certificate of authenticity issued by one of the three most recognized gemological laboratories worldwide: the GIA, the HRD and the IGI. These gemologists expertise the diamond and issue their identity card specifying all its quality characteristics as well as its authenticity. With this certificate, you are sure that diamond is a real natural diamond. On i-diamonds, we only market diamonds certified GIA, HRD and IGI. If you already own a diamond, when it weighs more than 0.30 carat, its value justifies that you have it appraised by one of these 3 laboratories. If you want to buy a diamond, starting at 0.30 carat, we strongly recommend that you do not do it if it is not accompanied by one of these 3 certificates. With this guarantee, however, you can be completely reassured. Note however that it is better to check that the number of the diamond delivered the laboratory is well laser engraved on the diamond rounder so as to ensure the proper match of the stone and its certificate.

What does a real rough diamond look like?

A rough diamond generally has an octahedral shape, similar to that of cubic zircon, but also that of moissanite, or else that of pyrite. To confuse them is so frequent. Some checks are needed to know if a rough diamond is true or false:
- study the shape of the diamond which must be as follows: Octahedron with eight triangular faces with twelve edges and six vertices, or cube with six square faces with twelve edges and eight vertices, or dodecahedron with twelve pentagonal faces with thirty edges and twenty vertices, or rhombododecahedron with twelve diamond faces with twenty-four ridges and fourteen vertices.
- use a diamond tester
- measure the refractive index of the stone using a temporal optical reflectometer which must be between 2,407 and 2,451.
- try to read transparently through the stone to be tested. If you get there, it means that your stone is not a rough diamond.

What is zircon and faux glass diamond?

Diamond can easily be confused with imitations, zircon is a perfect example. The natural gemstone of the silicates group, its high hardness and resistance make it a precious stone in jewelery, jewelery and watchmaking in the category of precious stones, as opposed to precious stones such as diamonds, sapphires, ruby and emerald. Of similar shape, with a strong index of refraction, the zircon is also declined in colors close to those of the diamond: colorless, white, pink, green, brown, red, yellow, blue, pink ...
Fancy jewelery is often made of faux glass diamond, also called rhinestones named after the jeweler of King Louis XV. It is a high-refractive glass paste material that takes on the appearance of colored diamonds after the addition of metal oxides. Another famous inventor is the Austrian Swarovski who has created crystals so similar to diamonds that they literally snapped up for gold!

What is zircon worth?

From 80 to 100 euros per carat, zircon is an imitation at an affordable price. This stone is however fragile, which is why it is often mounted in a closed setting. The deposits are mainly in Asia but are also found in France, in the department of Haute-Loire.

Is a diamond scratched a diamond?

How to know if a diamond is true or false? : by examining it in all its facets. The hardness of a material is its ability to resist scratching. It is measured using the Mohs scale which has 10 degrees, from 1 to 10. the softest to the hardest. The test consists of rubbing points of different hardness on one side of the gem, until one of them eventually scratches it. Result of the operations: the diamond has a hardness of 10! In other words, if using a magnifying loupe or a microscope, you see scratches or rounded edges and sharpened on your diamond, it means that it is not a real diamond.

Can a diamond break?

We have already mentioned above the exceptional hardness of the diamond which makes it the most resistant of all the minerals. But hardness does not necessarily mean strength, because this beautiful gemstone can break. Like a wooden log that can be easily slit in the direction of the height but not in that of the length, according to the plane of cleavage, the lapidary will know how to cut the diamond without risk to break. But that means that your jewel can actually break in case of shock from an unfavorable angle. It is therefore a doubly valuable object!

What is the difference between a diamond and a brilliant?

The common language frequently incorrectly equates the terms "brilliant" and "diamond".

They are rare stones (about 1 / 10.000) that take these hues following specific geological phenomena, resulting from a process of mixing of chemical elements and deformation of the crystal. Colored diamonds are the most expensive because of their rarity. More intense is their color, more expensive they will be, with prices of up to several hundred thousand dollars for stones of one carat or even less! They are classified by color grade according to the following standard which takes into consideration various factors such as tone and saturation:
