Gemology is the science of precious stones and fine gems.
A gemstone is a mineral hewn by man in order to mount it on a piece of jewelry or decorative object.
Among the most famous gems, we can cite the beryls (emeralds, aquamarines, morganite, heliodor), corundum (sapphires, rubies and sapphires), diamond but also tourmaline, quartz (amethyst, citrine, rock crystal rutilated quartz ..), garnets (Spessartite, demantoid, Tsavorite, Almandine, Hessonite, rhololite), feldspath (moonstones, labradorite ..), opals .....
There are also "hard stones" such as jade, lapis lazuli, malachite, rhodonite, the zoisite .....
Finally, organic materials such as pearls, mother of pearl, coral, jet, ivory, amber and even tortoise shell and shagreen (skin rays).

This science allows the graduate gemologist to distinguish between two stones, apparently similar but of different values (eg topaz and aquamarine) and identify all artificial and synthetic materials manufactured and used extensively in jewelry since the nineteenth century.

Gemology also allows analysis of the stones in depth and analyze their inclusions to confirm their origin (for a single stone, depending on the deposit inclusions can be very different).

The expert gemologist is able to give you the actual value of your stone according to various criteria such as:
- The intensity and vividness of color
- The purity and transparency for crystal gems
- The homogeneity of the color
- Hardness
- The size
- The weight of the stone
