Although Burma is more famous for rubies, it does produce a wild variety of sapphires as well. The Larson collection, assembled between the 1980s to 2008, included a good suite of this variety, of which this is one of the more unique and eye-appealing sapphire specimens. What an unusual, stout, blue and white marbled Sapphire from Burma! It has good hexagonal shape, its doubly terminated with one end having a better developed termination than the other and the crystal is very lustrous. The captivating mottling on this Sapphire is a result of a lighter and darker blue mosaic of Sapphire as well as inclusions of white Calcite from the marble host this crystal grew within. It is actually INTERGROWN with calcite, somehow, from the time it formed in the pocket and both grew contemporaneously out of solution, and then was frozen into marble around it. This is, also, a floater. The crystal faces are very reflective and the terminations each have the characteristic, subtle, triangular growth patterns on them. A few flecks of brown-black Biotite crystals are present on the backside. Rubies rule in Burma, but some great Sapphires originate from here and Bill was able to acquire some great ones like this hefty 141.5 gram, unique crystal. It simply stands out.
