Stilbite & Fluorapophyllite Crystals on Matrix
Jalgaon, Maharashtra, India
16.5 x 10 x 8 cm
An exceptional specimen from the historic Cavnic mining district in Romania. Sitting dramatically and at the center of the matrix is a sharp and clear Selenite crystal, which is doubly terminated ans 5.8 cm on edge. The crystal is both fronted and backed by smaller, doubly terminated Selenites. The matrix is brown, epimorphed Siderite, which  contrasts in form and color adding to the aesthetics of the specimen. In very good condition.
A highly lustrous and dazzling plate of centimeter size lemon yellow Sulfur crystals on matrix. In very good condition.
 A beautiful, teal blue, gemmy Fluorite from the Yaogangxian Mine in China. In fine condition.
A large showy, fine quality, multi-species association specimen from the famed Huanzala Mine in Peru. The main focus is a group of pale pink (Manganese bearing) feather like scalenohedra of Calcite forming a semi-spray measuring 3.1 cm across, associated with excellent quality, sharp, well formed, robust, smooth, metallic, dark silvery-grey colored crystals of Tetrahedrite measuring to 2.5 cm - along with ribbon like formations of white Quartz sitting on a matrix of additional sulfides, including Sphalerite, Galenna and Pyrite. This piece has excellent balance and aesthetics and anything like it would be very hard to find on the market.
A unique combination specimen featuring elongated, narrow, mostly tabular Cerussite crystals with pearly luster growing on  rolling mounds of tufted, acicular Malachite. The Cerussites range up to 1.4 cm in length, which makes them stand out easily. There are even some sparkly, micro Azurites that add color and accent.
Back Side

A nice specimen of beautiful, slightly resinous, spherical aggregates of translucent purplish-pink Smithsonite on matrix. In fine condition.
A fantastic eye catching Calcite specimen from a Pau locality in far southwestern France. It features a prominent, very sharp, highly lustrous, opic grade, colorless, modified Calcite scalenohedron measuring 4.2 cm across, sitting atop additional smaller transparent, water-clear Calcite crystals on host rock matrix. This is an outstanding quality specimen for the species and the locality, from a small find a few years ago.
A pretty polished nuggat of Malachite.
Aragonite var. Cobaltian
Richelsdorf District, Hesse, Germany
7.5 x 4.7 x 0.8 cm
Ex-Kay Robertson Collection
A very fine, thin plate of Aragonite var. Cobaltian. This is one of the more substantial and uniformly colored plates from the locality. The undulating surface teeters on the edge of being botryoidal and, certainly it has fine aesthetics for the species. An unusual rarity and is in fine condition.  
A wonderful display specimen of the elusive Calcites found around 2010 in a coal mine in Daye County Hubei, China. Very few are available on the market at present. It features several very well-formed, sharp, gemmy, lustrous, rich golden colored compressed trigonal crystals of Calcite measuring up tp 4.7 cm across, sitting on a thin layer of matrix. No major damage to the naked eye, and very aesthetic.

10.2 x 7.6 x 4.4 cm
Three, fascinating, multi-colored Fluorite cubes sitting on a sculptural, 
3-dimensional, milky Quartz crystal matrix. The surreal translucent Fluorites with satin luster faces, to 3.3 cm, have variable green cores followed by lighy purple shading, then stunning deep purple phantoms with green outer zones. Very aesthetic and from a small pocket in the mine in 2020. Even better in person ! In fine condition.
Calcite Crystals on Chalcedony
Jalgaon, Maharashtra, India
11 x 10 x 5.5 cm
Beautiful specimen of gemmy, complex, light amber colored Calcite crystals nestled on a matrix of lustrous Chalcedony. As a bonus - there are several smaller colorless gemmy Calcite crystals atop the main crystals. In fine condition.
