I bought these for earrings, but I haven't had a chance to use them, so I'm selling them. Size: Approx. 33 x 8 x 3 mm, with holes ✱Due to being natural stones, there may be scratches, chips, inclusions, and imbalances in the left/right sides or thickness. ✱I have uploaded images that are as close to the actual product as possible, but there may be slight color variations depending on your device. These are said to be precious petrified wood blue opals directly sourced from Indonesia. Ancient trees, over a long period of time, were fossilized by pressure and hydrothermal fluids, and the influence of copper minerals contained in the ground gives them their beautiful opal-like shine. Power stones that combine petrified wood and blue opal are said to fuse "stability and change" and "grounding and creativity," supporting mental stability (petrified wood) and talent development/intuition (blue opal). Specifically, they are expected to promote realistic growth by keeping you grounded, while also drawing out inner talents and creativity, bringing peace of mind and harmony in relationships.
