Idocrase

Idocrase is an older name for vesuvianite, a silicate mineral, green, brown, yellow or blue, first found at Mount Vesuvius. Wikipedia says Werner named it vesuvianite in 1795, that Haüy's name idocrase of 1796 is still in common use, and that jewellers sometimes use idocrase for gem-grade vesuvianite. Hall's entry is headed Idocrase and describes resinous, small transparent crystals with flecks, in green, brown, yellow, pale blue or red, from the United States. Hall says it links to the higher self, releases feelings of imprisonment, clears negative thought patterns and stimulates inventiveness and creativity. She also makes healing claims. These are Hall's claims, not established fact.
