SERANDITE

Overview:

Serandite was named in 1931 after J. M. Sérand, a mineral collector of West Africa who helped in the collection of Serandite on the island of Rouma, Los Archipelago, Guinea. It forms nice crystals that are often associated with other rare and interesting minerals.

Serandite forms a series with the mineral pectolite.Its unique salmon-pink color comes from a partial replacement of the calcium

in pectolite with manganese. It is found in several habits, from acicular to blocky to bladed, and crystals are occasionally twinned.
