This hand specimen consists of a cut and polished slice of tourmalinated quartz, is made up of tourmaline crystals that are included in a quartz matrix. The tourmalines that are embedded in this specimen are of the variety known as Elbaite, and most are quite small, not exceeding 0.1" (3 mm) in diameter. However, The two largest included Elbaites are of a variety known as Watermelon Tourmaline, as they are made up of a shell of green Elbaite that surrounds a pink Elbaite core. Neither of these inclusions are complete, and one is much less than 50% so. However, both the green and red tourmaline components are obvious. The edges of the specimen are rough and uneven, but the cut faces are both polished to a high gloss so that one can see the tourmalines with detail. Only the Watermelon Tourmalines are translucent to any degree, and the quartz matrix is milky and dimly transparent.
