Transparent pale smokey to citrine colored Quartz crystal from South Africa. An undamaged, doubly-terminated floater of top quality. I bought this as part of a parcel of Quartz crystals about 10-15 years ago and held onto it all this time due to it's beauty and quality. Better than photos!

Himalaya Mine, Mesa Grande, San Diego Co., California, USA

(click on an image to enlarge)

Colorful, doubly-terminated Tourmaline crystal from the Himalaya Mine. It has a flat, green termination at one end and steep, red termination at the other end. A classic Himalaya crystal that even has a slight bend due to fracturing and rehealing in the pocket. This was part of the collection of southern California collector Tim Sherburn. Tim bought the crystal in the UK while on a Fluorite mining trip and noted the uncommonly red coloration of the one termination (for the mine). There is a smaller side crystal attached that is also doubly-terminated. Undamaged and weighs 24.6 grams.

Large, complete tetrahedron of the rare mineral Chambersite. The crystal is 8mm on edge, making it huge for the species. The crystal is translucent purple in color and in perfect condition. Collected by Fred Pough in 1970. Ex. Chuck Trantham collection. This was the largest, best Chambersite crystal in the collection.

P190 - Sperrylite $2,200 available

Broken Hammer, Sudbury, Ontario, Canada
Thumbnail - 1 x 0.8 x 0.4 cm

(click on an image to enlarge)

Highly lustrous and bright single crystal of the rare platinum species Sperrylite from a lesser known locality. Sperrylite specimens are most commonly seen from Russia but the Broken Hammer deposit has also produced good crystals, though in much smaller quantity. This crystal even seems a few degrees more bright and silvery colored than the Russian crystals. Ex. Jon Sigerman collection.

P191 - Rhodonite sold

Morro da Mina mine, Conselheiro Lafaiete, Minas Gerais, Brazil
Thumbnail - 2 x 1.5 x 1 cm

Single gem crystal of Rhodonite from recent finds in Brazil. This is a complete crystal with typical stepped termination growth and small raised crystal growths on the wide front and back sides. It's perfect and undamaged, and transparent internally, weighs 9.1 grams. Superb color!

Beech Creek, Grant County, Oregon, USA

(click on an image to enlarge)

Platy white crystals of Levyne and Offretite in a vuggy Basalt matrix. Ex. Chuck Trantham collection. Collected by Chuck in 1966 on a collecting trip with Al McGuiness.

P193 - Wavellite $400 available

Laharran Quarry, Minane Bridge, County Cork, Ireland
Miniature - 5 x 5 x 2.3 cm

(click on an image to enlarge)

Translucent green Wavellite on matrix from Ireland. With Wavellite I appreciate both the perfect rounded crystals and the specimens that display the radial crystal structure. This specimen gives you both, with a perfect hemispherical 1.7cm wide 'gumdrop' adjacent to a partial crystal. It's also an aesthectic piece from an interesting locality. Ex. Tim Sherburn Irish collection acquired in 1996.

Los Lamentos, Chihuahua, Mexico
Cabinet - 9.5 x 6.5 x 4 cm

Transparent orange Wulfenite crystal, 2cm wide, on matrix with green Mottramite on Calcite crystals. Beautiful, colorful specimen and even the surface of the matrix sparkles with tiny Calcite micro crystals. Striking appearance and an uncommon Los Lamentos specimen. Acquired many years ago from Andy Seibel and has an old collection number painted on the back that predates Seibel.
