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.
Raipa Mine, Aija Province
7.7 x 3.9 x 3.3 CM (cabinet)
Superb cluster of classic form Axinite crystals with no matrix at all. The largest crystal here is about 6 CM long and the condition of all is excellent, with no damage. These are translucent with a few areas of transparency and the luster is very glassy. The purplish-brown color is distinctive from this find and this is an excellent esthetic cluster with many perfect, choice crystals in all directions. This was a large and important discovery which has provided some excellent quality pieces that were relatively affordable. Excellent value.
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.
A fine cabinet specimen that is far beyond the average Barite from Cerro Warihuyn. The Barite is a smoky golden color, very clear and mostly all transparent. The matrix is a mix of Dolomite and Rhodochrosite which adds a nice pink contrast. A few tiny dark Sulphide crystals are noted too, but they are minor in the composition. The free standing Barites are very fine for this important locality, 4.7 CM across with nice zoning. No damage to note except a small chip on the backside of the Barite that is not visible from any logical display angle. The presentation side is in perfect condition. Far better in person. This locale had produced lots of Barite and is world renown for them, this specimen is exceptional compared to the vast majority of the find.
Pyrargyrite on Manganoan Calcite
Pachapaqui District, Bolognesi Province
7 x 4.9 x 4.2 CM (cabinet)
Pyrargyrite crystals in small clusters and individuals are scattered on a pink Manganoan Calcite matrix. Individual crystals are up to 7MM. Some of the edge crystals have some chipping but the center portion is pristine. A few of the small clusters have the "raspberry" form and are hollow crystal aggregates best appreciated with magnification. A nice ruby Silver specimen that has a nice colored micro crystalline matrix as a contrast.
Bournonite, Quartz and Pyrite
Pachapaqui District, Bolognesi Province
7.2 x 5.4 x 5.2 CM (cabinet)
Late Summer 2018
Two-sided specimen with excellent sharp Bournonites on both sides. All the Bournonites show bright silver luster and twinning that in some crystals has the classic cogswheel habit. The side I consider the "front" or better display side has two main Bournonites that are perfectly formed and undamaged, set off by golden Pyrite and milky Quartz crystals. The "back" side has more nice Bournonites but there is some damage and contacts, (that is why it is the back of course). A few years ago matrix Bournonites of this quality were very rare and expensive when available but both China and Peru then began to produce these and they became very affordable. Now both these sources are not producing.
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.
