Euclase is typically colorless but is famous for the vibrant robins egg to deep indigo blue crystals it is found in. These crystals are prized as mineral specimens though they do not get very large- they only very rarely grow larger than 4cm.
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. Find out more!
Euclase is a very interesting gem mineral in the Beryllium family. It is similar to beryl and is often found along with beryl, topaz and chrysoberyl. It is often blue but can also be clear and slightly green. The crystals tend to be fairly small and not found in abundance, however, the deposits in the beryl rich nation of Zimbabwe are considerable in size. Gem crystals from Columbia and Brazil are some of the most prized.
