Demantoid mineral - You can buy these samples

Demantoid is a mineral, a rare green variety of andradite garnet, whose color is due to the admixture of iron and chromium. Demantoids have a higher dispersion than diamond, so the play of color when cutting in it is even higher than that of a diamond. The demantoid was first discovered in the Urals.

You can see a demantoid stone for sale and buy it in the Minerals of Russia online store.
