Natural Euclases Overview
 Euclase is not a well known gemstone, but is more well known by mineral collectors. It forms well formed crystals that occasionally have enough clarity to be cut as gems.
The sapphire blue and blue green colors of euclase are the typical colors of the gemstones. The crystals of euclase are commonly prismatic with slanted termination faces.
Unlike other monoclinic minerals whose crystals will commonly look like higher symmetry crystals, euclase's crystals are distinctly monoclinic due to the slanted termination. Nice crystals of euclase are much sought after by collectors.
Euclase is a species which owes its name to the cleavage which makes the faceting so difficult. Cut stones are very easy to fracture.
Can be confused with precious beryl, hiddenite, and sapphire. With radiation colorless euclase can be changed to blue.
