The combination of black and white diamonds is becoming increasingly popular. Not only does it add a touch of mystery to the jewel, it also boosts creativity and creates contrast. Black diamonds have this color because they have not crystallized. It's only since the 1920s that its value has been recognized and diamonds of this color have been used in jewelry, sometimes in association with the timeless and luxurious white diamond.

Individuals: why buy a GIA diamond?

Diamond is the hardest natural material, with a hardness index of 10 on the Mohs scale. It can only be scratched by another diamond, making it a highly durable material that will retain its beauty over time. Its value is very high, especially if it's a top-quality diamond certified by one of the gem specialist organizations, such as the GIA.
