A killer Beaverite in a highly esthetic and important specimen. This fairly rare Lead Iron and Copper specie is almost never in display grade specimens, it is usually just tiny crystals that are attractive only under the microscope. The Beaverite is in green and yellow botryoidal zones but also is in the rare red color balls and crystals which are dominant on this piece. The Beaverite is nicely contrasted with two generations of Calcite, the smaller being glass clear rhombs with the Beaverite visible through the crystals. Microscope exam finds areas of reddish Jarosite and what looks like Chenevixite in olive-green needle crystals. The first photos show what I consider to be the front as the Calcite make a great contrast, but the Beaverite is on all sides and the back (last photo) is super rich also. No matter the display side chosen this is a world class specimen. Ex John Marshall collection, I have not seen any better.
SOLD Schorl on Microcline
stock #SOLD 21.1-050
Hohenstein Massif, Omaruru District
8.7 x 7.6 x 3.2 CM (cabinet)
Sharp, lustrous Schorl crystals are scatted on a crystalized Microcline matrix. The Schorls are in several habits, well terminated with striated prism faces. In undamaged condition the specimen is well composed and is a choice example for this amazing locale. This was obtained directly from a group of "Small Miners" on the flanks of the Hohenstein just after it was extracted with laborious and careful hand work. The Small MIners have been one of the best sources of very nice yet affordable minerals today.

Silver Bill Mine, Gleason, Dragoon Mts. Cochise County
6.7 x 5.6 x 4.3 CM (cabinet)
Royal blue, velvety Rosasite fills an open cavity in this Gossan matrix. There are other areas of Rosasite on the specimen but the first images show the darker vivid blue that is much less common than the pale blue varieties. From The Silver Bill Mine of Arizona, this is well-known as a past producer of some attractive lead and copper minerals, and has become a classic USA locality. This is especially vibrant and a very good example for the region.
An excellent old Cornish Cerussite with sharp crystals to 2CM long. The crystals are all twinned with most showing a complete sixling habit. These look like six spoked gears when seen on end. The matrix is mostly a vuggy Quartz with micro crystals sparkling on most surfaces. For such a delicate mineral this is in good condition. Hard to know the exact age of this specimen, it has an old collection number on it, the mine was most active in the mid 1800's but there has been collecting activity in more recent years.
San Antonio Mine, Santa Eulalia, Aquiles Serdan
9.5 x 7.4 x 3.9 CM (cabinet)
new year 2021
A superb Smithsonite from the San Antonio Mine at Santa Eulalia, Mexico. An older specimen that ranks among the best for the locality. This could easily be mistaken for a fine Kelly Mine Smithsonite as the vivid color and silky chatoyance on the Smithsonite is a perfect match. The only clear differences from a Kelly piece is the matrix which on this specimen is mixture of Gossan with blebs of Smithsonite. It is also far less expensive than usual for a Kelly of this quality. Simply beautiful and even better in person, the luster and deep color are exceptional from this locale. A great addition to any Mexican collection or Smithsonite suite.
A classic form from the Herja Mine in Romania, this is a flawless and very sharp Stibnite ball. The individual crystals are highly lustrous, gun metal blue-black to silver that reflect colorful highlights in person. The matrix is a solid crystalline Silicate that is a complete floater, micro crystallized on all sides. Unusual and especially eye-catching in person. The ball is 2.3 CM across and impressively undamaged.
Miners Ridge, Red Mountain, Mendocino County
7.2 x 4.9 x 3.3 CM (cabinet)
new year 2021
A good sized blocky matrix with Mcguinnessite in rich crystalline crusts on several faces. Ex John Marshall collection, this is from the type locality area of Red Mountain. Close exam shows there are many tiny spheres and cups of blue green mineral, as well as some massive zones. A nice example of this unusual Copper mineral.
Cubanite twin crystals in a cluster with virtually no matrix. In fine condition as seen, such good Cubanite crystals have become quite rare as it has been over two decades since the last of this world class find. This one shows excellent golden luster and form, the largest crystal is a full sixling twin. It is very unlikely there will ever be more of this quality found. There are several localities in the world for this mineral but any crystals are very rare and almost all are micros. These Canadian specimens are the by a wide margin the best in the world, and good twins are especially scarce now.
