This has to be the prettiest chalcosiderite I can recall handling, with an intense sparkle and glistening surface, as the thousands of small crystals drape a 3-dimensional matrix plate. The heyday of the mining here was in the mid to late 1800s, and this relatively large, showy, cabinet quality display piece is something one does not see much of today. From the collection of ER Chadbourn, (1855-1920s) . See Min Record archives here: http://www.minrec.org/labels.asp?colid=1289

5.7 x 3.8 x 3.3 cm. Chalcosiderite is a rare mineral, a member of the Turquoise Group and is isostructural with turquoise. This showy, old-time specimen features two vugs richly covered with gemmy, forest-green, grape-like clusters of radial chalcosiderite blades on a quartz-rich matrix. This excellent specimen is from historic Cornwall, England and comes with an expertly handwritten, faded label from an older collection. The collection this came out of was a museum stash dating to prior to World War I. Wheal Phoenix in Cornwall is the Type Locality for chalcosiderite.

6.5 x 5.0 x 4.5 cm. Chalcosiderite is a rare mineral, a member of the Turquoise Group and is isostructural with turquoise. This fine, old-time specimen is from Wheal Phoenix in Cornwall, the Type Locality for chalcosiderite. The 3-dimensional, quartz-rich gossan matrix is loaded with vugs richly lined with gemmy, forest-green, grape-like clusters of radial chalcosiderite blades. This is fine material from this historic Cornwall mine and is certainly over 100 years old.

3.4 x 2.6 x 2.6 cm. Chalcosiderite is a rare mineral, a member of the Turquoise Group and is isostructural with turquoise. This fine, old-time specimen is from the West Phoenix Mine in Cornwall, the Type Locality for chalcosiderite. The vuggy front of the 3-dimensional, quartz-rich gossan matrix is richly lined with gemmy, forest-green, grape-like clusters of radial chalcosiderite blades on botryoidal goethite. The little quartz vein dividing the vug is a nice accent. This is excellent material from this historic Cornwall mine and is likely to be over 100 years old.
