Most of the 15 or so glassy and gemmy, intensely colored, blue aquamarine crystals rise vertically from a schorl and feldspar matrix. However, the largest of these aquas lies horizontally across the smack-dab middle specimen. It is doubly-terminated, and 5.9 cm in length, and beautiful. The schorls have good luster, are black and reach 2.0 cm in length. I really am impressed that almost all the aquas are terminated, with very little wear.
