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.
