PLUMBIAN (LEAD) FELDSPAR WITH QUARTZ AND GALENA – BROKEN HILL

$40.00

Product Description

For sale is a plumbian (lead) feldspar from Broken Hill, NSW. For sale is a green plumbian feldspar with galena from Broken Hill, NSW. Interestingly when this material comes out of the ground, it is colorless, when exposed to sunlight for a week or so it obtains its permanent green color. The name plumbian comes from the high lead content (for feldspar) approx 2%. This is most uncommon and I do not k now of anywhere else in the world this material occurs. This has weak fluorescence, of a blueish white. This is old material that today is no longer available and there will be no new material. Classic material!! Ex Trevor Williams collection (Broken Hill)
