Sharp, clear prismatic crystals of Valentinite scattered on and esthetic spray of Stibiconite. The Stibiconite has fully replaced the original Stibnite but the form is perfectly preserved. Despite the delicate nature of this specie, this specimen is in excellent condition, complete and undamaged. The Stibnites of Xikhuangshan are world famed, but the less well known, alteration species (like Valentinite) are also world class. This piece is ex Shields Flynn collection and looks good from every angle.
A neat variation of classic form from Mt St Hillaire, the flattened triangular Rhodochrosite Rhomb with some extra faces. This specimen here also has several tiny "normal" Rhodo rhombs. Lots of micro crystals on some faces and edges, including Polylithonite. In perfect condition by naked eye, only at 30X magnification are some rough spots found as is a secondary coating in a few spots. Displays well from most any angle, this is good looking on either side. An attractive large thumbnail.
Chapacase Mine, Tacopillia Dist, Tacopilla Province
2.5 x 1.7 x 1.4 CM (thumbnail)
A choice, rare example of the deep red Chromian variety of Wulfenite. Known from just three localities, the best specimens have all come from finds over 20 years ago in Chile. This piece is from those finds and shows classic form micro crystals on all sides of the matrix. Especially brilliant under the microscope this is in good condition and has well formed crystals with several habits densely encrusting. No eye visible damage but some micro chipping is found with 20X magnification on a few of the many otherwise perfect crystals.
A large glass clear Barite crystal that is complete and perfectly transparent. In very good condition and complete except on the bottom, this has a faden-like line seen in the center of the prism. Sharp and lustrous, a choice example from this less well known mine.
Wulfenite -Thin habit bright red
Jianshan mine (stone crack), Ruoqiang County, Bayin gholin prefecture
6.2 x 5.3 x 3.2 CM (cabinet)
Brilliant red Wulfenites with a delicate, paper thin habit that are free standing on a gossan matrix. Choice and esthetic example from the earlier finds at Xinjiang. The centers of many Wulfenites have a zoned coating on one side of the crystal, but others are unzoned. The delicate thin edges are mostly intact and undamaged but there is some damage on a few spots which is almost inevitable with such thin crystals. The color is as brilliant a red as is possible.
Grossular and Diopside
Jeffrey Mine, Asbestos
3.4 x 2.3 x 2.8 CM (miniature)
An attractive, complex specimen of lustrous cinnamon colored Grossular on prismatic Diopside crystals. A classic combination from the famed Jeffrey Mine. The Garnets are well formed and damage free, the Diopsides are well terminated with flat tops and also undamaged but are contacted on the outer edges. A choice miniature that has a fine color contrast. Better in person.
An incredible new find of Quartz with bright yellow tips that are now known to be inclusions of Humboldtine. We obtain this specimen and a few others in Colombia just over two years ago but the analysis was not validated until recently. This specimen is a radiating group of Quartz crystals on a small shard of matrix, and is in fine condition. The find has made big news in the mineral world and now seems to be fully exhausted, there were very few matrix specimens and most of these were very quickly sold. This specimen has misplaced and not put in our show display, it is one of the few left and we think maybe the only one on the web. Choice and obviously a very rare Quartz.
Grossular on Pectolite and Diopside
Jeffrey Mine, Asbestos
3.8 x 2.7 x 1.3 CM (small miniature/ large thumbnail (toenail))
Rare clear, zoned Garnets with green centers from Jeffrey Mine which are highly desired and unique to this legendary locality. In addition to being a choice and esthetic specimen these Grossular are vividly fluorescent, bright red in midrange and orange in longwave. In super condition even under magnification, this is a very fine example with a good mint green color overall even on the Pectolite and Diopside matrix. There was only a single find 30 years ago this type Grossular and is unique to the Jeffrey mine. A very choice miniature.
