Rosasite and Calcite with Hemimorphite
stock #22.1-182
Mina Ojuela, Mapimi
Durango, Mexico
7.6 x 7.2 x 4.3 CM (cabinet)
price: $1250
Fall 22

Super esthetic, a brilliant and rich Rosasite specimen from the famed Mina Ojuela. An outstanding example of this colorful Copper specie. A thumb-like projection of matrix extends out of an open cavity and is thickly decorated with blue-green balls of Rosasite and sheaves of clear Hemimorphite blades with sparkling small Calcite crystals. In perfect condition the vivid color and bright luster are top shelf. Most Mina Ojuela (and other localities) Rosasites are velvety to dull in luster. This piece with the addition of the Calcite next to and on top of some Rosasites is extra bright and eye-catching in person. The matrix gives a fine contrast.

Rosasite with Aurichalcite and Calcite
stock #22.1-185
Mina Ojuela, Mapimi
Durango, Mexico
5.7 x 3.6 x 3.1 CM (cabinet)
price: $320
Post Tucson 2022

Bright, sparkling and very vivid in color, this is an unusually pristine Aurichalcite/Rosasite combo from the great Mina Ojuela. Parts of the specimen are covered with fine needle Aurichalcite crystals and about half is a darker blue green of Rosasite. The Rosasite is also intergrown with Calcite and is visible inside the clear Calcite as well. This is a modern classic and very nice to see these species together in an eye-catching display.

Rosasite on Malachite over Mimetite
stock #17.1-533
Otjikoto Region, Namibia
5.3 x 4.4 x 3.2 CM (small cabinet/ large miniature)
price: $390
Early summer 2021

A choice example of Rosasite from Tsumeb, this is formed on and next to Malachite which has formed over Mimetite. Several Mimetite crystals have also formed on top of the Rosasite, adding a nice color contrast. The central "tower" of botryoidal Rosasite is about 2.5 CM (inch) tall, with a velvet luster that gives a nice focus to the specimen. Tsumeb is unquestionably the locality that has best mixed many beautiful secondary minerals of diverse elements, habits and forms.

stock #20.1-780
Mina Ojuela, Mapimi
Durango, Mexico
6.8 x 5.7 x 2.6 CM (cabinet)
price: $260
new year 2021

A flat matrix with one face well covered with botryoidal Rosasite balls. Excellent velvet luster and sheen, the color grades from a dark green to a lighter blue green. This is the old style of Rosasite from the 1960's the matrix is a soft gossan but is quite stable. The color and luster of a good Rosasite should look like this. This locality at one time produced lots of this distinctive Copper specie and some small finds still pop up, it has made these an excellent value for such an esthetic mineral.

Rosasite on Smithsonite with Calcite
stock #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

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
Otjikoto Region, 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.

stock #AX-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 #AX-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.
