MD-174600 - Hydrozincite, Calcite, Sphalerite - - Archived Picher Field, Tri-State District, Ottawa Co., Oklahoma, USA cabinet, 10.5 x 6.7 x 6.0 cm.
10.5 x 6.7 x 6.0 cm. A large plate from the famous Picher, Oklahoma Field of the Tri-State District. Three, large, to 4.5 cm, hydrozincite-coated gemmy, amber calcite scalenohedrons dramatically project upward, like snow-wreathed mountains from a flat plain of silicified limestone, which is very attractively complimented with smaller coated calcite crystals and gemmy, ruby-jack sphalerite crystals. Ex. George Feist Collection, #2993.
MD-180778 - Dioptase, Hydrozincite, Wulfenite - - Archived Mammoth-Saint Anthony Mine (Mammoth-St Anthony Mine; Mammoth Mine; St. Anthony Mine), St. Anthony deposit, Tiger, Mammoth District, Pinal Co., Arizona, USA miniature, 3.9 x 2.5 x 2.1 cm.
3.9 x 2.5 x 2.1 cm. Beautifully gemmy, emerald-green dioptase needles are concentrated near the crest of the wedge-like, mounded matrix. Wulfenites cover the entire piece and are coated with hydrozincite. Ex. John Ydren Collection.
MD-196847 - Hydrozincite - - Archived Ojuela Mine, Mapimí, Mun. de Mapimí, Durango, Mexico cabinet, 10.8 x 8.2 x 5.8 cm.
10.8 x 8.2 x 5.8 cm. Hydrozincite forms in the oxidation zones of zinc deposits as masses or crusts. This is a large and very rich specimen from Mapimi that is actually quite attractive, where little snowy balls of the mineral have formed in shallow recesses in a contrasting matrix of limonite. Ex. Stoudt Collection.
MD-201603 - Hydrozincite - - Archived Ojuela Mine, Mapimí, Mun. de Mapimí, Durango, Mexico cabinet, 12.4 x 7.5 x 6.8 cm.
12.4 x 7.5 x 6.8 cm. Hydrozincite - Zinc Carbonate Hydroxide – forms in the oxidation zones of zinc deposits as masses or crusts. Hydrozincite may be present on many specimens, but is usually unnoticed or assumed to be some other more common mineral, such as calcite or aragonite. This large matrix is richly peppered with tiny balls of snow-white hydrozincite, on a limonitic matrix; it is actually rather attractive, for a mineral that is not known for attractiveness. Ex. Consie Prince collection.
MD-210865 - Hydrozincite, Smithsonite - - Archived Tsumeb Mine (Tsumcorp Mine), Tsumeb, Otjikoto (Oshikoto) Region, Namibia miniature, 4.3 x 3.9 x 2.8 cm.
4.3 x 3.9 x 2.8 cm. Hydrozincite is an alteration product of smithsonite, sphalerite or hemimorphite. This fine specimen from the Tsumeb Mine features an aesthetic cluster of sharp, brown smithsonite crystals with a powdery dusting of gray hydozincite microcrystals on a nicely contrasting crust of calcite. The largest smithsonite rhomb, 1.8 cm, is perched at the top of the specimen. Ex. Rob Smith Collection.
