In January 2018, nine leading international diamond and jewelry industry organizations agreed on a universally-accepted diamond definition. Their goal was to help consumers avoid confusion given the proliferation of marketing terms they encounter increasingly in the marketplace, such as “cultured”, “laboratory-grown”, “created”, “cultivated”, “synthetic”, “simulated”, or “man-made”. These products, by definition, are not diamonds.

Definition of a Diamond
- A diamond is a mineral created by nature; a “diamond” always means a natural diamond.
- A synthetic diamond is an artificial product that has essentially the same physical characteristics as a diamond.
- An imitation diamond, also named a diamond stimulant, is an artificial product that imitates the appearance of a diamond without having their chemical composition, physical properties or structure.
- A gemstone is a mineral of natural origin that is used in jewelry for reasons of combined beauty, rareness and intrinsic value.
