Selenite Pieces 1-3"
Selenite Pieces 1-3"
Our Price: $0.40
Free Shipping

Selenite is a form of gypsum whose crystal structure forms long 'rods' or fibers that are capable of transmitting light via internal reflection much like fiber optic cable. These are short (1"-3" long) pieces of selenite, good for collections or experiments.

Not that selenite can be fragile and can 'shed' sharp fibers and so should be kept out of the hands of children. Price is per piece.
