We have for sale a supberb example of plumbian feldspar (lead feldspar) from Broken Hill, NSW. Among the amazing variety of Broken Hill minerals, this one is a real stand out, saturated green, translucent feldspar of this color is rare! These green feldspar”s are rather uncommon, I actually do not know of any other source of green microline feldspar in the world. This piece features the finest emerald green color, that was ever found! The plumbian feldspar sits on a bed of milky grey/white quartz, which its on a galena matrix. This feldspar was mined more than 40 years ago and nothing since (mainly due to the mechanization of the mining process). Interestingly this plumbian feldspar, is colorless to white when mined, but when exposed to light turns this very pleasant shade of almost emerald green. The change is permanent and does not fade even after many years!
