This is another highly interesting ruby from the Larson collection of Burma minerals: an irregularly shaped, part gem, bi-colored Burmese Ruby crystal with great waxy luster. It's difficult to describe its morphology as it is elongate and seemingly prismatic; however, the the prism faces are offset and discontinuous along its length and there is a crudely developed pinacoid at one end and a point at the other (all jargon speak for - very strangely grown!). The Ruby is two-toned red and purple with each color having gem areas; and then of course there is it's incredible luster. It's unusually long relative to its width with a crudely hexagonal outline. The Larson collection has preserved a number of such unusual mineral specimen examples of these gem species, that we seldom see. This variegated beauty has a mass of 13.2 grams.
