Textbook perfect, sharp and transparent, a single doubly terminated Selenite from the famed Naica Mine. This is a 1970s vintage specimen in fine condition as seen. There are a few wispy inclusions that are not visible on some display angles, the exterior luster is very glassy with a few areas with very minor frosting. Overall this is a choice example. The Naica mine produced a lot of Selenite in its day. Not much that came out was this fine, most had some damage or edge issues. Now that the mine is closed these better specimens are becoming treasures.
Chalcopyrite with Quartz
Yaogangxian Mine, Yizhang County
4.3 x 3.8 x 3.1 CM (miniature)
We do not see many good Chalcopyrites from Yaogangxian, although it was a common mineral there. This is an excellent, complete cluster of fine sharp crystals in outstanding condition. Very well defined striations, good patina and esthetic composition, this is all in all a choice piece. For a quite common mineral good Chalcopyrites crystals of this size are rare.
A dark Galena cube with complex face structures rests on a mix of Ankerite and druzy Quartz. The Ankerite is in two generations the older is translucent the newer is nearly black with inclusions and some faces are iridescent. A cute small cabinet (or large miniature) in perfect, undamaged condition from the historic mines of Nenthead.
Scheelite -Classic Korean
Tae wha Mine, Neungam-ri, Angseong-myeon, Chungju
4.2 x 2.6 x 3 CM (thumbnail)
A well formed cluster of elongated Octahedral Scheelites in a stack having selected coatings on some faces. The color seems nearly black but under strong light is seen to a dense dark purple and somewhat translucent. Some minor bruising can be found with magnification exam but it is not seen easily found by naked eye, this is in far better shape than most, some base and back contacts are also noted that are not damage at all. Displays very well from several angles.
Realgar with minor Stibnite etc.
Shaft #5, level 280, Baia Sprie (Felsobanya)
7.4 x 5.1 x 3.7 CM (cabinet)
Excellent deep red crystals of Realgar are both laying on and standing up from Quartz rich matrix. There are numerous areas of tiny needles of Stibnite throughout and a very thin seam that seems to contain a small bleb of crystalline Gold (seen at 40-80X). The main event here is the Realgar from the finds of more than a decade ago. In excellent condition overall but some edge bruising is seen with magnification on the smaller crystals. A very nice example from this find from a defunct location that is esthetic and reasonable.
Quartz Scepter showing epitaxy
Boron Pit, Dal'negorsk, Kavalerovo
Primorsky Kray, Far Eastern Region,
4.8 x 2.2 x 2 CM (miniature)
A new find from the great Dalnegorsk (this from the Bor pit). Choice sceptered quartz in excellent condition, with no chips or dings that hosts smaller Quartz crystals in epitaxial arrangement. The shaft of the scepter is composed of hundreds of tiny oriented small Quartz crystals stacked in perfect epitaxial alignment. These crystals and the "accessory" crystals are of the Cumberland or "Beta" type with little or no prism faces just two terminations joined. The smaller accessory quartz are also epitaxially oriented and have some inclusions and adhering matter that gives them a yellowish color. Some have called these Citrine but I think this color is simply a result of these inclusions. A few tiny crystals of Hedenbergite are on the base of the shaft as well. A choice, undamaged example and a nice scepter with amazing structure when examined closely.
N'chwaning Mine, Kalahari Fields, Kuruman
Northern Cape Province,
3.8 x 3.4 x 2.2 CM (small miniature/ large thumbnail (toenail))
A cute specimen of Olmiite crystals in spherical form on contrasting matrix. Nice luster and fair pink color, these were once all labeled as Poldervartites (a rare mineral at the time of the find) later re-studied and classified as Olmiite (also at that time a rare mineral). This discovery was sizable and enough good specimens found to allow collectors to own a nice piece without major financial pain. In good condition and a good value.
Okatjimukulu Farm 56, Karibib Region
3.1 x 3 x 1.7 CM (small miniature/ large thumbnail (toenail))
Flattened hexagonal crystal of deep purple zoned Apatite without matrix. From the finds several years back in the Karibib area of Namibia, this has an etched, frosted luster and good translucency. The crystal is not complete on all edges (typical for this find) but it is undamaged and shows complex recrystallization on some edges. The color is super intense in person, a very nice sizable purple Apatite.
