An odlyshaped specimen of native copper (with a spire and several other protrusios) has been entirely coated with a druze of cuprite crystals. These sparkle brightly, and in all of the protected crevices the tiny curpite crystals are transparent and well formed. Some cubic crystals are nearly a millimeter on a side, and some of them are transparent and large enough to show a deep red fire.
