✪ Andradite

Formula: Ca3Fe3+2(SiO4)3

Description: The individual demantoid crystals from these localities can reach more than 5 cm. Even though the majority of crystals are much smaller, there are surprisingly many crystals over 2 cm, often giving nice matrix specimens. The crystals are rarely transparent, and the locality is of limited interest for the gem industry.
