Unusual 'Angle-plated' Quartz

Item Description

These so-called "angle plated quartz" specimens are some of the most fascinating and unusual quartz varietals from ANY world-wide locality. They have also been called "reticulated quartz." They occur only in Randolph County, North Caroline and Pickens and Oconee Counties, Georgia. Mode of formation is imperfectly known. Formation theories include: 1) silica precipitated in cracks in red clay. The cracks are filled with micro-crystalline quartz and the "plates" are often encrusted with drusy quartz; or 2) pseudomorphs after calcite or barite. You can see drusy quartz on some of the plates. Whatever the mode of formation is, these are certainly a striking and rare quartz varietal. This sculptural piece has been sawed into its present exotic slab-like form and displays well without aid. I have not seen these for sale in a long time, and am actually curious myself as to what they may be worth! Unusual!
