This rather simple specimen consists of two Elbaite crystals that intersect each other at about a 75-80-degree angle. Both are in excellent condition, showing little, if any, human-induced damage. The smaller crystal has dimensions of 1.2 x 0.2 x 0.1" (3.0 x 0.5 x 0.3 cm). Its termination is almost completely enveloped by its intersection with the larger crystal, whose dimensions are 2.6 x 0.6 x 0.4" (6.6 x 1.5 x 1.0 cm). The larger crystal is complete, and has a good hexagonal prismatic form; a cross-section of the lower half of the crystal shows the rounded triangular shape that is very common in tourmalines. The upper half of its length expands towards its almost plumose termination. Both crystals have a green color that shows a tinge of yellow and show moderate transparence and patches of good clarity amid the many internal fractures and other inclusions. The lower half of the larger crytstal's length shows an outer layer of green material that is surrounding a nearly colorless core, and so can be classified as watermelon tourmaline. I think that the smaller, intersecting crystal makes the specimen much more attractive than it would normally be.
