This bicolor GemSilica displays striking contrast between saturated green-blue and lighter minty areas, caused by uneven distribution of copper-rich chrysocolla inclusions in silica. The zoning is a natural result of the way chrysocolla infuses the quartz during mineral deposition. Ray Mine GemSilica with distinct color banding like this is rare and increasingly sought after as sources have dried up. Collectors value these stones not only for their unique beauty but also for their historical and geographic significance.
From the Ray Mine in Scott Mountain, Pinal County, Arizona, USA.
