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 "entry-level" piece of Itoigawa jade. No waxes or other chemicals have been used, so you can enjoy the natural texture of the stone as seen in the photos for a long time. Please consider the photos when making your purchase. ● Size: Size 22 ● Width: Approximately 6.0mm ● Thickness: Approximately 3.5mm ● Weight: 3.90g ● Condition: Polished finish ● Other: No coloring, crack concealment, or waxing has been done. If you have any questions, please feel free to comment. Jade is by no means inexpensive, so we hope you will be satisfied with your purchase. Thank you for your understanding.
