Description: Ten quartz crystal specimens, ranging in length from 29 - 53 mm.
Most of the specimens have the iron oxide captured between layers of quartz growth, but some have it on the outer surface. Most have lovely phantoms, including a small "glitter" phantom.
All of the specimens have nicks, varying from minute to small, with two being long nicks. There are also several (mostly neat) pressure marks, and damage where they parted from their matrixes.
