Blue Mountain Jasper Rock slab 31
Blue Mountain Jasper is considered to be one of the premium jaspers that has been a long time favorite with the lapidary community. Known for its blue-green/gray orbs, it is a very hard material that takes a superior polish. It also comes in other shades, mainly brown and olive, and makes exquisite show pieces and finished cabs. The status of the "mine" where it has been obtained over the years is now unclear and new material may not be available anymore.
