Fluorite with Quartz

Description

Group of cubic Fluorite crystals with edges bevelled by rhombododecahedral faces, showing an unusual habit for the species due to the balanced growth of these isometric forms. The rhombododecahedral faces are smooth and polycrystalline, with pronounced curvatures on both faces and edges. The Fluorite has a very deep and vivid color, between deep blue-violet and navy blue, and contrasts beautifully with the milky Quartz matrix. The Quartzs show two distinct generations of growth. Large primary quartz crystals are partially covered by a second generation of fine sparkling quartz, with the blue fluorite crystallizing later over the quartz. A fine example of the complex hydrothermal crystallization characteristic of the Huanggang deposit
