Euclase is derived from the Greek word EU KLASIS, which means “Easily Fractured". This name was given by the French priest and minerologist René Just Haüy because the perfect cleavage of euclase makes the crystal fragile which can fracture very easily.

Euclase is a beryllium aluminium hydroxide silicate mineral and is related to beryl. Euclase forms in long narrow fine quartz crystal prisms.

Euclase is very rare and therefore it is a highly desirable mineral among collectors. Though its hardness is similar to beryl which is 7.5 on the Mohs scale, it is extremely brittle due to its perfect cleavage which makes it impossible for gemstone cutters to work with it.

Euclase is transparent to translucent and closely resembles the pale blue of the aquamarine. However, euclase may also be clolorless, white, light green, dark blue, purple, light purple and bluish green. The blue variety of euclase which is also known in the gemstone industry as the “Blue Emerald” is the most valuable and sought after.

Euclase can be found in the southern Urals of Russia where it was originally discovered. Some of the most beautiful euclase are found in Auro Preto, Brazil where they are found with topaz; in Zimbabwe, in Chivor, Colombia and very few specimens of euclase have been found in the Austrian Alps. [Note: highly transparent, blue and aquamarine-colored euclase crystals have been found in the Colombian Chivor mines.]

Due to their rarity and beauty, euclase are extremely expensive, more so than diamonds, rubies and sapphires. A beautiful and fine specimen of euclase is known as Estefania and it is prized over one million dollars.

Euclase is a love amulet as it is very calming and it induces a peaceful and loving environment. It also encourages communication in a non-confrontational manner. It transforms negative energies to positive and enhances your ability to be empathetic and compassionate to ourselves and others. It is advisable to wear raw or in an uncut crystal form in order to harness its powerful innate energy.
