1970s


Valencianite was at one time considered a distinct species of Feldspar. It was later discredited; however, there is a note on mindat that recent research suggests it may indeed be a distinct species of K-Feldspar. On the specimen, the Valencianite crystals are mostly covered with white colored Quartz crystals. Down near the bases of the Quartz and Valencianite crystals are green colored Milarite crystals. There is also light orange/tan colored Calcite crystals which cover much of the bottom of the specimen.

Condition: Good

Flaws: A few of the smaller Quartz crystals are broken and a couple of the terminations of some of larger Quartz crystals have very minor chips.
