Andradite Andradite is named after the Portuguese mineralogist, d’Andrade.

This is one of the rarest and most sought after garnets. There are no major sources of andradite and the supply is limited to small deposits.

Its dispersion is much higher than any other garnet and even much higher than diamond. The dispersion is usually masked by dark body colors but small, light colored gems are dazzling!

The variety dematoid is colored green by chromium. This gem is always in high demand.
