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.
Gem clear, bright and lustrous Rhodochrosite crystals from the now classic Uchucchacua Mine in Peru. The main crystal on the matrix is just over 2 CM long and there are several other smaller crystals as well. Protected in a narrow vug the main crystal is quite perfect and damage free. While Rhodochrosite can be found all over the world there are no more than 3 places that have ever produced crystals of this size, quality and habit. Of those localities Uchucchuacua is the only place that still is an occasional producer. Well beyond average quality yet still relatively affordable for a fine Rhodo.
Sizable doubly terminated Rhodochrosite crystals sitting on contrasting matrix. These are the "fat Scalenohedral" habit from Uchucchacua and are translucent to transparent with the largest crystal 2.1 CM. The presenting face of the specimen looks in very good undamaged condition but the crystals do have contacts and chipping on the backs and sides so this is not for perfectionists. Depending on the display angle this can look quite perfect however. The crystals have some faces showing complex striations but others are smooth and lustrous. A great value for the size, color and form.
Dramatic miniature with brilliant deep red gemmy Scaleneohedral Rhodos in perfect condition. An outstanding Uchucchacua piece with top luster and form. No chips, dings or cleaves even under strong magnification, which is very rare. Older specimen that is much better in person, this may remind you of a fine Wessels mine specimen. A very choice, competition grade miniature.
An outstanding cabinet display piece of fine, large (to 4.5 CM) crystals of iridescent Chalcopyrite on contrasting Sphalerite. Although Chalcopyrite is a common mineral, great crystals especially large ones are surprisingly rare. The patina and metallic color play make this especially attractive. An older Casapalca specimen in fine condition overall, with a few small chips mostly on outer edges. As Chalcopyrite is very brittle it is rare to have such large crystals in this fine condition.
Metallic and bright lustrous these very sharp crystals are sprinkled with a few small quartz and pyrite crystals. Individual tetrahedrons up to 2.7 CM are jumbled in a complex arrangement on this matrix plate. In fine condition overall for this delicate mineral, only one crystal has an edge bruise, all others are perfect, complete and pristine. Really hard to find this level of quality at any price.
A choice single scalenohedral Rhodo crystal with a small bit of matrix adhering to the back and bottom. Super bright color and sharp, glassy prism faces. The lower termination has some contacts on the back side but otherwise this is in super fine condition and the front side displays very clean as seen. An excellent Peruvian thumbnail that looks a bit like a South African. Choice.
A choice small Rhodo specimen with nice color and in fine condition. The matrix is a dark Goethite that is covered with tiny colorless Fluorite crystals that look black due to the matrix showing through. The Rhodos are mostly scalenohedral with truncated tips some of them showing some "wheat sheaf" habit. Good coverage as well makes this a nice display piece.
