Gemmy, transparent, high luster calcite from the famous Quincy Mine. Upon close examination there are numerous tiny malachite-coated copper inclusions on the surface. This variety of calcite is one of the rarest forms seen on the market. A choice miniature in excellent condition. Ex. Cranbrook Institute of Science #207-446; to Louis Lafayette Collection #1199. Note: Mr. Lafayette acquired this for the wonderful price of $1 at one of the Cranbrook Auctions - I am certain he was pleased.
