Terminated prismatic lawsonite crystals on a schist of glaucophane and massive lawsonite. The lawsonite crystals are pinkish white, up to 1 cm in length, and show striations along the long axis of the crystals. Bits of fibrous blue-black glaucophane throughout, with a couple slightly richer veins on the backside (child photo). Don Windeler collection, acquired 2007 from Elaine Oyler estate sale. Ex-Ed Oyler collection; I suspect from the hand-written note that he collected it, but cannot verify.
