Although euclase can resemble beryl in its appearance, that is where the comparison ends. Unlike beryl, euclase contains water, has a monoclinic crystal system, and a higher specific gravity. Only occasionally do its well-formed crystals have sufficient clarity to be cut as gemstones. Crystals are commonly prismatic, can be long or short, and are striated. Because of their rarity, gems with good clarity command premium prices. Most material is colorless to pale blue or pale green, but colors can range from blue to blue-green, green, yellow, white, colorless, and, rarely, purple.

It's clear, sparkly, and a 7-1/2 on the Mohs scale. It comes in an array of compelling colors - from blue to blue-green, green, yellow, white, colorless, and, rarely, purple.

Euclase can resemble beryl in its appearance, but in no other way are they related. Euclase contains water, has a monoclinic crystal system and a higher specific gravity than beryl. It is only occasionally that its well-formed crystals have enough clarity to be cut as gemstones.
