Ettringite, Thaumasite, Gaudefroyite and Calcite (Charlie Key)

Item Description

A glowing canary-yellow ettringite crystal is nicely accented by a matrix of a water-clear, smoky, thaumasite crystal, sparkly black gaudefroyite crystals and calcite crystals on this very fine combination thumbnail from the Charlie Key dealer stock. Thaumasite is an uncommon member of the ettringite group. The slightly tapered, sharp termination compliments the translucent shimmer with electric sheen of the crystal faces.
