These are classics from the 1960s and early 1970s, though most were sadly destroyed or damaged over the years due to the inherent fragility and softness of the species. This one displays very nicely and is "nearly" a competition quality specimen save for minor contact on the left edge, this cerussite twin exhibits all the best qualities of lead carbonate from this deposit. It has glassy adamantine luster and gemminess combined with a lovely heart shape and gemminess - is absolutely limpid. If not for the small contact (which is NOT damage, but is just where it grew against matrix), this would be a world class thumbnail at 10x the price based on how others have sold as they turn up in old collections or museums. And, it really DOES display well, especially when lit up so the light reflects inside and comes out with rainbow colors.
