A superb cabinet specimen of this very rare Copper Molybdenite ex John Marshall Collection. Sharp and well defined platy crystals are arranged in a radiating flower-like fan on contrasting matrix with zones of Cuprian Powellite. Good specimens of this quality are practically impossible to find now unless an older collection is being sold off. The original locality had an area less than a square meter that held a few clusters and that was it. That was more than a quarter century ago, this is now recognized as perhaps the most beautiful new mineral found in decades. Aptly named for the discoverer, Terry Szenics, pieces of this quality were limited to a few flats and were sold very quickly. This piece is far better than average and has a very well articulated crystal spray that reaches 3 CM. Excellent deep green color (some were much more pale) and bright luster. Since the original find this mineral has only been found in one other locality (Arizona) as micro crystals mostly under 1 MM and poorly defined. This is certainly the best specimen we have had.
Langite PS after Molybdenite
Jardinera #1 Mine, Inca de Oro, Chanaral Province
5.3 x 3.7 x 2.7 CM (small cabinet/ large miniature)
An incredible, rare and exotic pseudomorph, Langite replacing bladed crystals of Molybdenite. This was collected by Terry Szenics at the Jardinera #1 mine (where he discovered his namesake mineral Szenicsite). This was X-ray confirmed in 2009, and retains the Szenics label. There are areas of a dull grey material which seems to be altered Molybdenite that has not yet been replaced by the Langite. This is a remarkable, odd and rare specimen, the best example I have seen, very few were found and all were collected several years ago. The green blades reach 1.6 CM across and are distinct. A fine addition for any collection of Pseudomorphs.
Super bright color and sparkling luster, this has a tiny bit of Malachite remaining but most all is pure Chrysocolla. The Chrysocolla shows the elongated forms of primary Malachite crystals which it has replaced. The brilliant blue fingers on this piece are radiating outward from a Gossan matrix and are fully encased with clear, sparkling Quartz. Fine and delicate, in excellent condition and with strong display impact.
Brilliant sparkling blue Chrysocolla overgrown by gem clear druzy Quartz. The Chrysocolla has replaced earlier acicular crystals of Malachite. The individual needles reach 1.5 CM A single broken needle off to the side seems to show a core of Dioptase but we are told these are in fact Malachite, the core area is rather gemmy and very bright. No matter what the original material this is very esthetic and totally different from any other Chrysocolla. An attractive, intriguing and unique Copper specimen!
