This specimen is absolutely superb for several reasons: its richness, history, and crystal size among them. It is a large cluster of already remarkable lanarkite crystals from the type locality, and of both display size and aesthetics. The lanarkites are draped with a druse of susannite crystals (also type locality) to 3 mm - considered extremely rich overall. A small yellow macphersonite crystal is attached at the front (looks like a little yellow wulfenite, center-middle in photo). This specimen is a MAJOR classic rarity of the mid to late 1800s, seldom seen in this quality even in the most major Museum collections. I have certainly never seen the like for sale. The piece was exchanged out of the collection of France's National Museum of Natural History and made its way into the Lindsay and Patricia Greenbank collection (of English and Scottish minerals) by the 1990s. It was bequeathed to the museum in about 1900 as dated by the antique museum accession label in the handwriting of Professor Alfred Lacroix. It had been in the noted collection of Charles Frossard, a noted French collector living in the Pyrenees, by the end of the 1800s. The specimen overall is a full-on display-quality miniature.
