This polished pegmatite slab contains sections of several Elbaite crystals. Though they are far from complete, their rounded triangular and hexagonal shapes denote their trignonal form. Most are "watermelon tourmalines", as they are made up of a pink core surrounded by a green shell. The pegmatite is made up of quartz, feldspar, and muscovite, and has been ground and polished to a moderately high gloss.
