Euclase is said to have several important metaphysical properties. Euclase connects with crown, heart, and throat chakras. It is said to help wearers of the stone to break bad habits, maintain focus, increase ability in communicating clearly, and to heighten mathematical and other left-brained skills.

Euclase is popular because of its beauty and rarity. Few other pegmatite minerals have as rich of a blue color. Its hardness makes it so it is sometimes used in gems, though these are rare due to the strong, perfect cleavage of Euclase. These gems are very expensive and treasured by collectors though. Even colorless Euclase is in demand because of its pleasant luster which is similar to “silver” topaz from Namibia.
