[GOLD STONE] Crystal Bracelet, Iris Quartz, Natural Rainbow, 12mm, Rainbow, Natural Stone, Power Stone, Inner Diameter: Approx. 20cm

■ Size: Diameter approximately 12mm (±0.5mm), Inner diameter approximately 200mm (±5mm) Rainbow quartz is a type of quartz that contains cracks within it, causing it to emit rainbow-colored sparkles when light reflects off the cracks. Not all cracks in a quartz crystal emit rainbow-colored light; only cracks with complex optical interference effects cause the light they reflect to appear as brilliant rainbow colors. When sunlight is reflected rather than artificial light, the rainbow colors are even more brilliant. Rainbow quartz is popular not only for its beauty, but also for its rarity, which comes from the fact that it contains cracks that meet certain conditions.
