This very pretty Oregon Sunstone is an AA bicolor pink/green with a nice little bit of copper schiller.

Oregon Sunstone is classified as a cuprian laboradite feldspar and rates between 6.5 and 7.2 on the mohs hardness scale. It is durable enough for a ring if protected well, like a bezel setting, but probably best as a pendant.

Some jewlers shy away from Oregon Sunstone because of its perceived fragility, but still work with stones like Tanzanite, which are equally as fragile. Given that Oregon Sunstone is a lot less expensive, the risk/reward payoff to me is a no-brainer.

This particular stone measures 11.6x9mm and weighs 3.44ct.
