A superb gemmy Microlite crystal with very lustrous faces and good color. These were tested to be Fluornatromicrolite but they are also often labeled as "Microlite group" which is a bit less exact. No matter the name, the quality and large size is exceptional and the addition of glassy clear Topaz on the specimen adds some interest too. It is rare to see a crystal so perfect and at 1.5 CM it ranks as a giant for this usually non esthetic specie. From the Urandu mine finds of 2017, this is as fine as has ever been found in Pakistan and for that matter worldwide.
Spessartine on Galena
Broken Hill, Yancowinna County
New South Wales,
5 x 4.3 x 3.4 CM (cabinet)
A killer bright red well formed Spessartine Garnet perched on classic Galena matrix from Broken Hill. The Garnet is nearly 2.5 CM across the long dimension, which is huge for this locale and the color, luster and condition are superb. No damage or repairs, the back of the Garnet has a clean contact but is complete and with no chipping even under 30X magnification. Sits well for display without props, this is far better in person. This almost certainly came from the North mine but the old labels are not specific, so we are listing it as simply "Broken Hil"
A complex small specimen with two main large Bismuthinite crystals that are covered with tiny crystals of Stannite and Marcasite. The specimen also has areas of Chalcopyrite as well as some tiny needle crystals of Bismuthinite that seems to be a later generation. A choice example of the thicker type of Bismuthinite crystals and a nice association of these two Sulfides. From a recent find that was premiered in Munich in October 2019.
A huge somewhat crude but very sharp Helvite series crystal is nestled in a cluster of prase type Quartz. These Helvite crystals are often zoned in this locality and may contain all members of the series (Danalite, Helvite and Genthelvite) in a single prism. This one has clearly also had some secondary alterations, and some parts of the Helvite faces have been encrusted with tiny Quartz crystals. The termination has an extra touch - a purple octahedron of Fluorite perched near the tip adds contrast. No damage, the Helvite is nearly 4 CM tall which is very large from any locale and especially big for Huanggang. An early specimen (prior to 2008) from this now prolific mine. An impressive example of this locale and specie.
A well crystalized cluster of Gypsum I(Selenite) with rich green inclusions and encrustations of the rare mineral Herbertsmithite. This find has produced what are certainly the most esthetic examples of this specie as Herbertsmithite is not usually a "display" grade mineral. Recently Herbersmithite was found to have unique properties of changeable magnetism and with quantum spin properties. This was picked up in some of the popular media and somewhat exaggerated as news, even being called a "new form of matter". There was a brief period where tiny crumbs were being sold for high prices. Despite the inaccurate hype this is a remarkable mineral and on this specimen it is actually attractive.
SOLD Bournonite - Cogswheel type crystals
stock #SOLD 19.1-856
Colavi Mine, Machacamarca district, Cornello Saavedra Province
3.1 x 2.6 x 2.4 CM (small miniature/ large thumbnail (toenail))
A fine complete cogswheel cluster of Bournonite crystals that is perfect on all sides, undamaged and with classic gunmetal luster. Bournonite is a delicate mineral and perfect clusters of this sort are quite rare. A tiny bit of adhering matrix gives some nice contrast. This is a very fine and unusually sharp specimen from Bolivia that really looks just like a vintage Herodsfoot specimen. From recent mining this is obviously far less expensive than the English classics!
A delicate slender scepter of well formed Amethyst rises from a cluster of smaller crystals. Very fine esthetics and good color in perfect condition. The scepter is included by red needles of Rutile best seen in the clear parts of the head. This specimen also has the rare hexagonal hole or negative crystal in the top of the termination, this is especially impressive with magnification. Despite the small size this has a strong visual impact and is especially choice on close examination.
SOLD Scheelite with Fluorite
stock #SOLD 19.1-854
Dongpo Mine, Yizhang County, Chenzohou prefecture
3.7 x 2.8 x 2.3 CM (miniature)
Sharp white octahedral Scheelites cover most of this matrix along with a sharp Fluorite and some scattered Calcite crystals. In fine condition from the Dongpo mine, a locality better known for large Fluorites. This is from a small find made this fall, these are the first Scheelites I have seen from Dongpo, It has some similarities to an older find at Huangshaping mine not very far away.
