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.
Euclase is BeAlSiO4OH – a fairly simple monoclinic beryllium aluminum silicate phosphate. It has a hardness of 7.5 on the Moh’s hardness scale and a very strong perfect cleavage perpendicular to the c-axis of the crystal. Euclase is bi-axial, meaning it has two optic axes each with different indices of refraction, though for this mineral both of these numbers are very close to each other- around 1.65 or 1.65 times the refractive index of water.
