Rhodochrosite -Scalenohedral crystals
stock #12.1-273
Uchucchacua Mine, Oyon Province
Lima Department, Peru
4.2 x 4.1 x 2.8 CM (miniature)
price: $650
Spring 2019

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.
Barite on Dolomite and Rhodochrosite
stock #AX-12-503
Cerro Warihuyn - Miraflores, Huamalies Prov.
Huanuco Department, Peru
10.9 x 7.9 x 6.4 CM (cabinet)
price: $725
Dec 2018

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
stock #18-AX-10-796
Pachapaqui District, Bolognesi Province
Ancash Department, Peru
7 x 4.9 x 4.2 CM (cabinet)
price: $400
Dec 2018

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
stock #18-AX-10-906
Pachapaqui District, Bolognesi Province
Ancash Department, Peru
7.2 x 5.4 x 5.2 CM (cabinet)
price: $280
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.
Rhodochrosite -Scalenohedral crystals on Quartz
stock #18.1-172
Uchucchacua Mine, Oyon Province
Lima Department, Peru
4.7 x 3.8 x 4.4 CM (miniature)
price: $1550
Spring update

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.
Barite -window pane type
stock #18.1-170
Cerro Warihuyn - Miraflores, Huamalies Prov.
Ancash Department, Peru
7.8 x 4.7 x 4.5 CM (cabinet)
price: $450
Spring update

Transparent, sharp and lustrous Barites in rosette form on minimal matrix. Undamaged and with a light smoky color this has several excellent display angles with good impact. The digging at Cerro Warihuynan has been a major discovery of fine Barites. Even in the flood of good specimens, this piece is far better than typical, a very choice example with a price to quality value ratio that is hard to find these days.
Chalcopyrite on Sphalerite w. Pyrite-
stock #17.1-A19-098
Casapalca Mine, Casapalca, Huarochiri Province
Lima Department, Peru
9.8 x 7.2 x 5.2 CM (cabinet)
price: $480
new june 17

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.
SOLD Rhodochrosite- gemmy crystals on Sulphide finger
stock #SOLD 17.1-136
Uchucchacua Mine, Oyon Province
Lima Department, Peru
4.5 x 2.1 x 2 CM (miniature)
price: $0
Spring 2017

As fine as it can get! Perfect crystals of gem clear Rhodochrosite studding a slender finger of Sulphide matrix which gives great contrast. Elegant crystal arrangement with top color and luster, simply a top miniature specimen that is 360 degrees viewable. The terminations of the Rhodos are all quite perfect too, even under strong magnification. Clearly a fine competition grade miniature. Ex M. Budil, F Gaboury, from a find at Uchucchacua, Peru in 1999. It is incredible that even with this many crystals the specimen is still perfect and undamaged.
