Langite PS after Molybdenite
stock #18.1-622
Jardinera #1 Mine, Inca de Oro, Chanaral Province
Atacama Region, Chile
5.3 x 3.7 x 2.7 CM (small cabinet/ large miniature)
price: $390
Dec 2018

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 There are areas of a dull grey material which seems to be altered Molybdenite that has not yet been replaced by the Langite.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.
Chromian Wulfenite
stock #18.1-621
Chapacase Mine, Tacopillia Dist, Tacopilla Province
Antofagasta Region, Chile
2.5 x 1.7 x 1.4 CM (thumbnail)
price: $110
Dec 2018

A choice, rare example of the deep red Chromian variety of Wulfenite. Known from just three localities, the best specimens have all come from finds over 20 years ago in Chile. This piece is from those finds and shows classic form micro crystals on all sides of the matrix. Especially brilliant under the microscope this is in good condition and has well formed crystals with several habits densely encrusting. No eye visible damage but some micro chipping is found with 20X magnification on a few of the many otherwise perfect crystals.
Chrysocolla (Druzy overgrowth of Quartz)
stock #18.1-432
Inca De Oro, Chanaral
Atacama Region, Chile
2.7 x 2.5 x 1.6 CM (thumbnail)
price: $110
Late Summer 2018

Bright sparkling blue Chrysocolla thumbnail with very pretty form. Druzy Chrysocolla is found sporadically in small amounts at just a handful of locations worldwide, and the electric color has made it highly desirable for lapidary as well as an esthetic, collectable mineral. The matrix of this piece is a solid dark gossan that has a scalloped surface. The Chrysocolla in this case is likely a pseudomorph of earlier Malachite crystals. Displays well with more impact that usual for the size.
Chrysocolla - drusy Quartz overgrowths
stock #18.1-433
Inca De Oro, Chanaral
Atacama Region, Chile
4 x 2.6 x 1.7 CM (miniature)
price: $280
Late Summer 2018

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.
Krohnkite - large crystals, rare habit
stock #A18.1-AX- 18-037
Chuquicamata Mine, Calama, El Loa Province
Antofagasta Region, Chile
4.7 x 3.6 x 3.4 CM (miniature)
price: $580
Worldwide mix summer

Bright, large blocky habit Krohnkite crystals in a cluster with minimal matrix. From the type locale, Chuquicamata which is the only place where this rare Copper Halide was ever found in such fine crystals. While and non micro crystals are rare most of those are fibrous growths or slender clusters. Prismatic habits like this are far more uncommon, and were all found long ago. Most of the existing specimens were collected long before 1934 (the early 1900 era was most productive) but it is probable a few came out later. The zone where these were found was long ago disappeared, consumed by the largest open pit mine on the planet. Only seen now from old collections.
Quartz on Chrysocolla Pseudomorphs
stock #18.1-130
Inca De Oro, Chanaral
Atacama Region, Chile
9.1 x 6.8 x 5.2 CM (cabinet)
price: $800
Spring update

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!
Copper and Gold on Quartz
stock #17.1-AX-19-322
Andacollo Mine
Elqui Province, Chile
3.6 x 2.3 x 2.1 CM (miniature)
price: $850
May 2015

An exceptionally rare combination of well crystallized Gold on well crystallized Copper. This is a nice Copper specimen with elongated spinel twin crystals in esthetic curving "horns" and some distinct texahexahedral crystals. What makes it special is the addition of several areas of well crystallized native Gold. The gold is best seen with a loupe but some is eye visible with well developed branching sprays and bright yellow metallic color tucked in several areas on the specimen. This little known mine is one of the few locales that ever produced Gold on Copper, and by far the most attractive. There were not many pieces in the find, these are are now almost impossible to find. This one is the best I have seen.
Chrysocolla (psudo after Atacamite)
stock #0129-JM-3875
La Farola Mine, Cerro Pintado
Copiapo Province, Atacama Region, Chile
9.4 x 8.1 CM (cabinet)
price: $100


Brilliant rich blue color, densely deposited crusts on matrix. The Chrysocolla is in the form of rounded tube like structures and plates. From J. Hyrsl minerals (Czech Republic) who ascribes the form to a pseudomorph of Atacamite. Very attractive deep color.
