This particular specimen came out of a very large piece that a friend of mine bought and then acid-bathed. It consists of two pieces of Elbaite "watermelon" tourmaline that partially intersect each other at a 35- to 45-degree angle. They are both nearly identical in size and proportion, measuring about 1.3" (3.3 cm) long and 1.0" (2.5 cm) in diameter, and occur as portions of trigonal pyramidal crystals. Neither piece shows a natural termination, and both have breakage faces that show their multicolored cross-section. Each of them has a very dark green skin that surrounds a pale blue core, and both show faint translucence only near the breakage plane, so it is difficult to determine how intensely they are internally fractured. There is a crust that partially covers most of one of the crystals- it is made of almost microscopic muscovite platelets that are intergrown, mixed with more small, black tourmaline crystals.
