An old specimen of this rather scarce Zeolite specie from the most prolific locality at Sasbach, Germany. Many small cavities on all sides hold white linings of tiny Faujasite crystals and botryoidal masses. The crystals are typically very tiny octahedra best seen with good magnification. Some small Augite crystals are also present. This is not an "esthetic" specie with crystals typically under 1 mm, but this is a good example none the less. Ex. R and A Palmer collection from the Joe Mandarino study suite.
From the zone in Brazil famed for Amethyst geodes, this is something very different from almost any other Quartz. A pair of spindle-like growths of Glauberite that has been altered to and overgrown by Quartz. These are perfect, complete all around, with tiny transparent smokey Quartz sparkling on all sides.
Jeffrey Mine, Asbestos
3.5 x .6 x .7 CM (small miniature/ large thumbnail (toenail))
new year 2021
A single glassy prism of yellow-green Vesuvianite from the great Jeffrey Mine. In perfect condition sections are gem clear, transparent and other parts are translucent with wispy internal veils. One edge of the prism has a dusting of tiny transparent Vesuvianites that are nearly colorless. Somewhat dichroic, this more yellow hue is much less common than the more apple green colors. The Jeffrey Mine produced many fine Vesuvianites, certainly the world's best but also was the source of many rare and unique colors. This is a nice and relatively affordable crystal, impressive for the size and nicer in person.
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.
