They are Diamonds. For over fifty years, man has succeeded in creating diamonds in the laboratory that are completely identical to those mined from the bowels of the Earth. They have identical chemical, physical, and optical characteristics. Initially used only for industrial purposes, today, thanks to the excellent quality achieved, they find full use in the world of jewelry. It's important to remember that in the laboratory, a rough diamond is obtained, which then, as with mined diamonds, is entrusted to the expert hands of cutters who will cut it into various shapes, such as round brilliant, pear, oval, and many others.

No. They have the same chemical, physical and optical characteristics as mined diamonds.

The Diamond Created in the Laboratory (or lab-grown diamond) It is a diamond in all respects with identical chemical, physical, and optical characteristics. Otherwise, the term diamond could not be used to identify it. This is why, according to international standards and all gemological institutes, the term diamond can be used.

The only difference is the environment in which they were formed and their cost. Lab-grown diamonds grow in just a few weeks in laboratories where all stages of production and processing are controlled. Mined diamonds were formed millions of years ago deep within the Earth, and their provenance, processing practices, and the environmental impact of their extraction often give rise to controversy.

No. They are practically identical. Traditional tools make it impossible for a jeweler and a gemologist to determine whether a diamond is lab-created or mined. Only an expert gemologist, using sophisticated equipment, can identify a diamond's origins.

Absolutely not. Just like mined diamonds, a diamond can take on different colors and contain inclusions during its formation.

Technically speaking, it's correct to call them synthetic, as any substance obtained in a laboratory rather than found in nature is defined as synthetic. However, in common parlance, "synthetic" is often associated with something fake, or an imitation, a simulant. A lab-created diamond is not a fake or an imitation: it is a diamond, unlike synthetic zirconia, YAG, or rhinestones.

Diamond is simply carbon that crystallizes in nature at high pressures and temperatures. Humans have succeeded in reproducing these conditions in the laboratory using two main methods:

• High Pressure High Temperature (HPHT): Reproduces the natural conditions of high pressure and temperature to transform graphite into diamond.
  
• CVD (Chemical Vapor Deposition): starting from a diamond “seed” in a growth chamber, a gas containing carbon (e.g. methane) is used which, at moderate temperatures and pressures, releases carbon atoms that bind to the seed, causing the diamond to “grow”.

If you love the sparkle of diamonds, being identical, the light emitted by a Lab-Grown jewel will enchant your eyes. A jewel should excite, gratify, and make you feel good every time you wear it, regardless of the material it's made from.

Lab-created and mined diamonds are identical; they have the same hardness, identical chemical, physical, and optical characteristics that will never change over time. A diamond, whether lab-created or mined, is forever.

Kleed Jewels In addition to being accompanied by a certificate of authenticity, they are also accompanied by an International Certificate issued by the International Gemmological Institute (IGI). The certificate includes a description of the jewel, a photo, and the characteristics of the gems.
