These are small peridot crystals, also
known as olivine. Peridot is a semi-precious stone and it has been
valued throughout the ages for it's vitreous luster and emerald-like
color. Peridot has volcanic origins and these crystals were screened
from a deposit of volcanic "olivine bombs". These crystals have been hand-picked for their size and color. All of these are approx. 2mm in size, or larger.
