The stunning Fluorite crystals measure 4 x 3.6 x 3.2 cm and very glassy and lustrous. The impressive, sharp, tabular structure in the middle may be a barite pseudomorph or an unusual tabular Quartz crystal.

Manganoan Calcite with Calcite & Quartz
Huanggang Mine, Hexigter, Inner Mongolia A. R., China
18 x 17 x 14 cm
A spectacular, large, two-sided, combination specimen. Features a dramatic, 12.7 x 10.5 cm rosette of lustrous, pastel-pink Manganoan Calcite disks perched atop a sloping field of glassy, translucent Quartz points. A sharp, 3.8 cm on the diagonal, Manganoan Calcite rhomb on the lower left side is a very nice accent. The back side is quite different! The parallel-growth disks of the rosette are set on an earlier generation, impressive, 10 cm on the diagonal, tannish-pink, Manganoan Calcite rhomb. Quartz is on the specimen matrix and the 6.7 Quartz point is a nice accent. In very fine condition.

Pretty formation of two generations of Manganoan Calcite on Quartz and Sulfides.
Eye appealing coverage of light blue to cream colored Chalcedony over Barite crystals. Possibly a partial pseudomorph.

This is definitely the best Vivianite specimen I have ever offered on my site. It has super gemmy emerald green crystals (to 2.2x0.8 cm) aesthetically arranged by nature on a Siderite matrix - much better than the more common, fragile Limonite material. The Vivianite crystals are in pristine condition with nice accenting dotting of Siderite crystals on some of the terminations. A Beauty !!!
