Cobaltocalcite

Cobaltocalcite is a rare calcite colored by traces of cobalt. Especially fine material has a vivid reddish-purple color and excellent translucency.

We have had samples certified by GIA, who has issued special reports on our larger cobaltocalcites as especially notable specimens. We can obtain reports from GIA on gems that have not yet been certified. See a sample GIA Cobaltocalcite Report
