This rather odd specimen consists of a section of a classic watermelon tourmaline crystal whose rubellite core has been mostly replaced with Lepidolite. The lepidolite retains its pale gray-pink coloration, pearly luster, and micaceous, flaky consistency, but has taken on the trigonal prismatic form of the tourmaline. There is much damage to the piece, though it is difficult to separate damage done after mining to that which occurred before. A substantial portion of the green tourmaline "skin" is still present, as well as a small amount of the original rubellite core material. A small spray of broken albite blades is attached, but there is no other base or host rock present.
