This ring was created from a raw stone sourced from Omi, Itoigawa. The ring is made from a raw stone that is generally white (gray), black, and green, with the black parts being black jade. This ring has a gentle feel due to the handmade imperfections. However, it does contain some thin cracks. The product price reflects this, and there is no guarantee against chipping or cracking. Please consider this an "experimental piece" of Itoigawa jade. No waxes or other chemicals are used, so you can enjoy the natural texture of the stone as shown in the photos for a long time. Please consider the photos when making your decision. ● Size: Size 14 ● Width: Approximately 4.1mm ● Thickness: Approximately 2.9mm ● Weight: 1.87g ● Condition: Polished finish ● Other: No coloring, crack concealment, or wax treatment has been applied. Please feel free to ask any questions you may have. Jade is by no means inexpensive, so we hope you will be satisfied with your purchase. Thank you for your understanding.
