Lemanskiite with Lammerite and Olivenite
El Guanaco Mine, Guanaco Santa Catalina, Antofagasta Province
5.5 x 4 x 3.8 CM (cabinet)
new year 2021
A rich showing of crystal clusters of the rare copper specie Lemanskiite from the type locality. Lemanskiite is a fairly new mineral recognized as unique in 1998. This piece also has a sizable ball of crystallized Lammerite (about 9 mm across) and a few sprays of Olivenite as well. The Lemanskiite is in micro crystals up to 2 plus mm radiating clusters that can be seen as distinct crystals by naked eye, but under magnification these are super impressive. This is a choice specimen of both Lammerite and Lamanskiite.
Barite - sugarcube habit
Murray mine, Sugarbowl pocket, Independance Mts. District, Elko Co.
3.4 x 2.6 x 1.8 CM (small miniature/ large thumbnail (toenail))
new year 2021
Brilliant sparkling thumbnail to toenail with excellent form. A modern USA classic, this is a cluster of blocky Barites (Barytes) that are well covered with a druzy Quartz. Highly lustrous, this looks just like sugar cubes. From the one time find more than 20 years ago at the Murray Mine(Elko, Nevada, USA) from a remarkable pocket called the "sugarbowl". In perfect condition and far more bright and glittery in person.
Bright yellow crystals of the rare Lead Uranyl Phosphate Parsonite are on several surfaces, some mixed with green Torbernite. Usually Parsonite is a specie for micromounting but this is a colorful and displayable specimen. Strong magnification also shows what appears to be some orange and yellow crystals of Dewindtite, another rare specie associated with Uraninite. This is not confirmed by x-ray, but this mine is one of the best sources of the specie and this appears to match well. The zones of Parsonite are quite large and and seen by naked eye. The tiny crystals with magnification show they are in radiating sprays and clusters of needles. This was previously in the collections of Kay Robertson and Terry Szenics who are both well-known as knowledgeable, selective and tasteful lovers of minerals.
An older specimen from the Wutong Mine (China) with very good pink to red Rhomb crystals. Close exam with magnification will find several very small crude crystals and masses of Silver on the underside. This is certainly not a display grade Silver specimen but more of interest as an accessory mineral on the Rhodos. This find was an important discovery and in the first zones exploited the crystals usually had a rhomb form while later finds tended to be more flattened or disk shaped. Overall in very good condition and with with some faces showing etching and brighter luster.
An open cavity fully lined with sharp, clear Tarbuttite crystals and with close exam some white acicular Scholzite crystals. Tarbuttite is quite rare worldwide but from two localities it was found at one time in good amounts and in high quality. The old Broken Hill (Zambia) and the Skorpion Mine in Namibia have both produced some well-crystallized and attractive specimens. These locales had a completely different look. This Broken Hill (Kabwe Mine) piece has lustrous, gemmy clear and very sharp crystals that are in fine condition overall and contrast with the matrix well. Choice and displays very well.
Uvarovite - emerald-green Garnets
Saranovskii Mine, Saranovskaya, Permskaya Oblast, Middle Urals
7.3 x 6.8 x 1.7 CM (cabinet)
new year 2021
A flat plate of matrix with the display face richly covered with vivid green Uvarovites. The larger crystals tend to be a more dark green and are especially lustrous. These Russian crystals are almost always rather small though this piece has some individuals to 2+ mm which is larger than usual. Uvarovite is one of the less common members of the Garnet family, there are just three locations that have ever produced good or sizable crystals though the specie is known from other locations. This has been sawn on the back (not visible from the front) to help remove this without damage. The intensity of color and bright sparkle of these Russian specimens makes them stand out as a good value that is noticed even among other colorful minerals.
Wulfenite and Mimetite
Rowley Mine, (Reliance Mine), Theba, Painted Rock District
2.3 x 1.4 x 1.1 CM (thumbnail)
new year 2021
A classic Rowley Mine combo, window pane clear Wulfenite with bright red balls of Mimetite. From the specimen extraction efforts of 2015 this is a colorful, delicate and bright thumbnail. The Wulfenite is clear yellow but the transparency carries the orange to red color of Mimetite so it looks at first glance to be orange. This has minimal matrix and while not fully perfect is still a striking, attractive but affordable specimen. The mine has been closed for a while and it may never again produce, but it has made a mark as one of the world's best Wulfenite locales with a unique look.
More Cash Lode, Montezuma District
3.4 x 2.5 x 2.3 CM (small miniature/ large thumbnail (toenail))
new year 2021
Matildite is a fairly rare Silver Bismuth Sulfide. Best known as micro crystals from several classic German Silver mines, it is especially uncommon in the USA. This is not a pretty specimen but a nice rarity for a Silver specie suite. It has naked eye visible masses and a few very tiny spots of crude micro crystals of silvery Matildite mixed with Pyrite.
