Anglesite
stock #17.1-693
Tsumeb
Otavi-Bergland district, Oshikoto, Namibia
2.1 x 1.3 x .8CM (thumbnail)
price: $180
Pre Holiday 2017

A transparent Tsumeb Anglesite crystal with the look of a Moroccan specimen. Smokey cognac color and zoning a well as unknown inclusions add a nice look to this crystal. On close inspection the association of Chalcocite and Posnakite micros and the unusual face coatings confirm that this is from Tsumeb. Glassy and sharp, there is some light edge bruising but the crystal is complete and terminated. A less common form and habit this is an early vintage piece much better in person.
Rosasite with Calcite rosettes
stock #17.1-AXA-4 243
Mina Ojuela, Mapimi
Durango, Mexico
8.8 x 6.6 x 6.2 CM (cabinet)
price: $975
Pre Holiday 2017

Colorful and choice, this is a striking specimen. Velvety Rosasite on a gossan matrix is decorated with bladed Calcite crystals some of which form Rose like structures. The Calcite range from glass clear when small to milky whitein the larger blades. Several are twinned and the whole composition is very fine. The condition is excellent for such a delicate piece, there is a single cleave and very minor chips to be found on a careful exam but in a normal display nothing is noticeable. This is the best example of this find and habit I have seen, from 2013. The Calcites are mostly thin flattened rhombs or flattened hexagons with sharp, transparent or translucent edges. Far better in person.
Pyromorphite -Vintage two toned from Classic locale
stock #1028-JM-486
Alston Moor
Cumberland, Cumbria, England
8.8 x 7 x 3 CM (cabinet)
price: $2200
Pre Holiday 2017

A very fine, old Pyro having two generations and two colors of crystal growth. A significant specimen, Ex John Marshall Pyromorphite collection, collected prior to 1900. John obtained this in 1972 at the Boylston Massachusetts Library auction of a collection originally donated in 1900. It took him a lot of research and trips to the British museum to clarify the locality. This is described on his detailed collection card included with the specimen. Nearly perfect, very little bruising as seen, most crystals are well defined and lustrous. A very choice example from a less well known classic locale.
Barite on Fluorite with stepped faces
stock #17.1-690
Emilio Mine, Lorone, Colunga
Asturias, Spain
9.3 x 7.8 x 4.7 CM (cabinet)
price: $490
Pre Holiday 2017

Sharp Fluorite with classic form of complexly stepped cubes (distinctive of some Asturias specimens) is the base for a spray of flat Barite crystals. Choice display specimen that is better in person, the Fluorite has a pale violet-blue color and a few purple phantoms. In fine condition damagewise, the delicate Barite blades are surprisingly all intact. Looks good from all sides this has no point of attachment it is fully crystallized on all faces. A remarkable specimen from all angles.
Fluorite with Quartz and Dolomite
stock #17.1-689
Shangbao Pyrite Mine, Leiyang
Hunan, China
4.6 x 3.2 x 2.2 CM (miniature)
price: $640
Pre Holiday 2017

A fine and esthetic cluster of zoned Fluorite cubes in a delicate array. Minimal matrix, the cubes are very well separated and freely formed. Some faces show a light frosting others are more transparent and inside the cubes are swirls of deep purple with many inclusions of micro quartz prisms. With good magnification small movable bubbles are noted and the interior landscape is impressive too. Overall in outstanding condition damage wise, the corners and edges show some stepped growth but no damage. Several angles for display work well and have a quite treelike form. From mining in 2006 this style of specimen is no longer produced.
Rhodochrosite - Scalenohedral gemmy group
stock #17.1-639
Hotazel Mine, Kalahari Mg Field
Northern Cape Province, South Africa
2.2 x 1.3 x 1.3 CM (thumbnail)
price: $490
Pre Holiday 2017

Brilliant red color and perfectly transparent gem crystals in a cluster with unusual form. This specimen has grown in close contact with many other crystals (now gone) that have created the unusual geometry of this piece. Unsually contacts are not esthetic but these are in an odd way very sculptural. Some very small edge rubs are seen with magnification and one cleaved spot is eye visible so this is not a perfect (or expensive) piece that can be still be displayed without any of imperfections showing. Recently even poor examples of this sort of Rhodo have become incredibly expensive. This reasonably priced but intensely red crystal has an odd form and just a few rough spots. Very good value for one of these.
Galena- Skeletal and chain growths with Sphalerite, Chalcopyrite and Quartz
stock #WAM-17.1-688 (27-134A)
9th of September Mine, Madan, Rhodope Mts.
Smolyan Oblast, Bulgaria
6.9 x 4.5 x 3.4 CM (cabinet)
price: $1150
Pre Holiday 2017

Amazing form! The Galenas here show many unusual habits, the epitaxial chains are most eyecatching but the hoppered and skeletal crystals are also very fine. Remarkable too is the lack of any visible damage. We have handled a lot of fine Bulgarian specimens but this one stands out as a very choice piece for esthetics and combinations of well crystallized but bizzare forms. From finds in 2014 I have not seen any newer material quite like this.
Calcite with Sphalerite and Quartz etc.
stock #A-27-132
Borieva Mine, Madan, Rhodope Mts.
Smolyan Oblast, Bulgaria
4.6 x 3.9 x 3.5 CM (miniature)
price: $170
Pre Holiday 2017

A delicate specimen in excellent condition with very pale pink (mangano) Calcites on a matrix of needle Quartz, lustrous Sphalerites and Pyrite. An attractive and nicely composed specimen from the great Madan deposits of Bulgaria. To my taste the Sulfide deposits of this region have produced the most esthetic examples of many species. This is a small but striking piece with quite remarkable slender Quartz that are decorated with tiny crystals of Sphalerite as well.
