[GOLD STONE] Iris Quartz Artificial Crack Rainbow Crystal Bracelet 16mm Natural Stone

Grain diameter: 16mm (±0.5mm), Inner diameter: 165mm Rainbow quartz is a type of quartz that has cracks within it, causing it to emit rainbow-colored sparkles when light reflects off the cracks. Not all cracks in quartz emit rainbow-colored light; only cracks with complex optical interference effects cause the reflected light to appear as brilliant rainbow colors. The cracks are artificially created. The quartz is natural. The product you receive will be identical to the one pictured.
