Gem Focus May 2021: Feldspar

Gem quality feldspar species are more commonly sought as collectors’ stones and seldom for jewelry since they are not very durable. They tend to be colorless, light yellow, sometimes gray. The unusual variety of microcline feldspar, which displays an attractive greenish blue color is called amazonite.

Pink Diaspore

Much of the pink diaspore rough seen to date has areas capable of cutting medium to large size stones that are eye clean and in many cases loupe clean

Red and Hot Purple Tourmaline

Unheated and vividly colored purplish red cuprian tourmalines have gained a special niche and become more of a collector’s stone, while rubellite remains one of the favorite tourmalines in the market.
