Rosasite on Smithsonite with Calcite
stock #18-AX-19-146
Silver Bill Mine, Gleason, Dragoon Mts. Cochise County
Arizona, United States
4.3 x 3.8 x 2.2 CM (miniature)
price: $90
Dec 2018

Spheres of blue Rosasite scattered on Smithsonite and some Calcite. A good locality piece that is especially fine under magnification. The Silver Bill mine has a long history but is not very well known outside of Arizona. It has been a source of Wulfenite and other species as well as Rosasite.
Rosasite on Malachite ps. after Azurite crystals
stock #17.1-697
Tsumeb
Otavi-Bergland district, Oshikoto, Namibia
3.6 x 2.6 x 2.4 CM (thumbnail)
price: $550
Pre Holiday 2017

One of the more famed Pseudomorphs from Tsumeb is Rosasite replacing Malachite that has replaces Azurite crystals. This is an excellent example with a thin outer zone of Rosasite that has several small Calcite rhombs sprinkled on the surface. Attractive and now quite uncommon, the main crystal is in perfect condition. Other crystals on the back and bottom side are broken showing the malachite core, does not affect display. A big thumbnail with a lot of good visual impact.
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.
Rosasite
stock #Alec 4-249
Mina Ojuela, Mapimi
Durango, Mexico
4 x 4.1 x 2.9 CM (cabinet)
price: $390
new june 17

A free-form sculpture of velvety Rosasite from Ojuela. This seems to have formed over a gossan matrix most of which has been etched away leaving this botryoidal mass of Rosasite. Fine color, this is nearly all Rosasite not just a thin coating. From a find in 2012 that was one of the best pockets of Rosasite seen in decades, this is a very attractive piece in great condition.
Rosasite with Calcite and Malachite
stock #Alec 11-254
Mina Ojuela, Mapimi
Durango, Mexico
6.5 x 3.9 x 3.5 CM (cabinet)
price: $160
Spring 2017

A really colorful dark green Rosasite with Malachite on a matrix of clear rhombs of Calcite. The specimen is covered with small spheres and botrytoids of velvety Rosasite intermixed with Malachite. The condition is choice and the contrast with the white Calcite crystals sets everything off well. A little different esthetics than the usual Rosasite.
Rosasite on Malachite- "treelike"
stock #A-4-246
Mina Ojuela, Mapimi
Durango, Mexico
6.9 X3.9 CM (cabinet)
price: $600


A fine and esthetic "treelike" or cruller specimen of velvety Rosasite on and mixed with malachite. There are some small Calcites as well for a little extra sparkle. Mina Ojuela has produced the best Rosasite known, usually in finds often decades apart. This was from the last find in 2011, mostly low quality but with a few outstanding pieces. I selected this from a small group of the very best. While not large, it has great color, form and eye appeal that make it an affordable yet worthy addition for any collection.
