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.
SOLD Wulfenite and Mimetite
stock #SOLD 15.1-854
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.
An old classic, a dark schist matrix hosting several vivid green hexagonal crystals. Very good transparency on the most prominent prism, these tiny gem crystals are nicely scattered, exposed and terminated with flat faces. An old collection number (313) on the specimen indicates this was likely from the Lechner Collection. The original European labels are lost but this has the Immer Cook label from the early 1960's when he was the neighbor to the Schortmann Brothers mineral dealership. One small crystal is bi-colored with a white zone. Though the crystals are tiny they stand out well from the dark matrix.
Cubanite with Calcite
Henderson Number 2, Chibougamau
1.8 x 1.5 x 1.1 CM (thumbnail)
new year 2021
A fully twinned Cubanite crystal from the great find at Chibougamau almost 25 years ago. This Cubanite has a small spray of flat Calcite crystals on one corner giving a nice accent. There is no matrix. A circle of an iridescent alteration in the very center of the radiating arms is quite unusual. This patina is the classic brassy golden metallic. The front side is complete all around with the radiating point off center but crystallized on the fat edge. The back is contacted though not broken and about 50% complete. One small chip is noted on the display face that is visible by naked eye but can be hidden by creative mounting. Cubanite is very delicate and some damage is normal, this is not perfect but has far less than most. The find at this mine (Henderson #2) was by far the greatest ever with the best Cubanite crystals ever seen. These are only available from old collections and the most desirable are the flat twinned crystals that show the radiating or star striations.
