M441 -
Quartz Crystal - Double Terminated, Thumbnail (Tibet).
Quartz. Silicon dioxide. Hardness 7. Beautifully formed,
double
terminated quartz crystals. In comparison to all the quartz
crystals, the double
terminated crystals are a rarity. Double
terminated means the crystal terminated, or came to a point, at both
ends as if the crystal was formed out from the center. On a few of
these specimens you can see a small rough-like cavity in the center
of the crystal to substantiate the theory that these crystals formed
by "growing" out from the center.
These small double terminated crystals are sometimes water clear and
have been called "diamonds" due to the exquisite clarity and the
crystal formation. Clear quartz, or crystal quartz, is used as a
semiprecious gemstone. These crystals are a favorite
among metaphysical practitioners and rock collectors.
