Sharp and gemmy red Rhodochrosite crystals on a contrasting matrix. The crystals are mostly formed as Scalenohedral but take a few other forms as well. Uchucchacua is one of the worlds best Rhodo localities for Scalenohedrons, but not as well known (or expensive) as South Africa. Several crystals are partly coated with a thin crust of what seems to be Calcite and makes a nice contrast.
From the type locality area for Wulfenite, this is a very choice, classic Lead secondary specimen. About a dozen distinct octahedrons of Galena are sparkling with hundreds of Cerussite crystals scattered on the faces. The spaces between the Galenas are full of orange to red Wulfenites in a blocky form. One of the great classic mineral localities, important since the early 14th century. In 1556 Agricola described the locality and methods in his famed "De re Metallica" . The mines closed for good in 1993, but left a great legacy of minerals and helped develop many methods in use today. This specimen is in remarkable condition, is far more attractive in person and a fine display quality Galena much better than most seen in collections from here.

Sparkling pink balls of Thompsonite on a contrasting matrix- a very attractive specimen of this usually drab mineral. The outer surfaces of the balls are covered with tiny needle crystals that make the luster far more bright than most typical Thompsonite. This is from a small find about 6 years ago that was unlike any Thompsonite found before or since, and were perhaps the best specimens ever. We sold this piece some time ago it is now back and we are happy to have it. One edge of this piece has balls that show the inner structure along the side. The overall quality, color and condition is excellent and this is a super example of this more uncommon Zeolite. A colorful and attractive addition to any suite of Zeolites or Indian minerals.
A flower form composed of thin blades of Pyrrhotite crystals esthetically perched on sharp crystals of Arsenopyrite. A rare specie from the famed Yaoganxian mine these were found almost 2 decades ago, we have not seen any since. The main flower is 3 CM across with a dark metallic patina. The Arsenopyrite crystals are highly lustrous and sharp. Overall in fine condition, one edge of the main flower has what seems to be a small old rehealed break or edge contact, not at all distracting, otherwise the display side is perfect. A very choice Sulfide from anyplace and a superb piece for the legandary Yaoganxian or for that matter all of China.
