Very impressive form and esthetics for any Aragonite. Ball like radiating clusters of crystals in elongated translucent prismatic form twins that are joined in a chain. Some internal coloring on some areas adds a nice contrast. Fine condition overall, a few chips are seen on the backside but otherwise this is a 360 degree piece, displayable from most any angle.
Sierra de la Cruz, Municipio de Sierra Mojada
4.8 x 4 x 3.1 (miniature)
Large red-purple "Raspberry" Garnets on contrasting matrix from Coahuilla. The crystals reach 1.4 CM and some are intergrown. Aside from some contacts the crystals are unusually complete and well exposed on the matrix. This locale was still active and producing until about 4 years ago. This style of Garnet is unique to this zone which over the years produced many fine specimens. A good, affordable specimen.
3.4 x 2.4 x 1.5 CM (small miniature/ large thumbnail (toenail))
A super clean, brilliant toenail sized Dioptase from finds at Kaokoveld in 2012. Very sharp and lustrous crystals in excellent condition and having an esthetic arrangement. While Dioptase is known from quite a few localities in the world but this sort of very fine specimen is from either Tsumeb (closed forever) or Kaokoveld, bot being in Namibia. Top emerald green color with transparent areas set this apart, better in person.
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.
