Chalcedony / Agate pseudomorph after Fluorite (ex Charlie Key Collection)

Item Description

A rare phenomenon in the mineral world in the form of Chalcedony / Agate replacing cubic Fluorite crystals from the old Blinkpan locality in Namibia. The name Blinkpan isn't really used for this material anymore, and it's more correctly from the Ysterputs Farm 254. This piece is loaded with fine quality, sharp, translucent, beautiful blue-lilac colored pseudomorphs of Fluorite which have been replaced by Chalcedony / Agate (or some other form of cryptocrystalline Quartz) on matrix. For the most part, the piece is in great shape, with the only real damage being around the periphery where the piece was removed from the pocket. These came out years ago and are rarely seen on the market today. This particular piece was priced at $950 in our inventory from many years ago, so I have to believe it would be valued higher today. From the Charlie Key personal collection. Charlie is arguably the most successful dealer of the second half of the 20th century, along with being the namesake for TWO mineral species (Keyite and Ludlockite).
