This ring was created from a jade rough stone from Omi, Itoigawa. The base of the rough stone is white, including black jade, and the green color comes from omphacite. However, it contains thin cracks. The product price takes these cracks into consideration, so there is no warranty for chipping or cracking. Please consider this an "entry-level" Itoigawa jade item. This ring has a gentle feel due to the handmade imperfections. Since no chemicals such as wax are used, you can enjoy the natural texture of the gemstone in the photos for a long time. Please consider the photos and other details. ● Size: Size 12 ● Width: Approximately 7.6mm ● Thickness: Approximately 3.7mm ● Weight: 4.03g ● Condition: Polished finish ● Other: No coloring, crack concealment, or wax treatment 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. We are also selling this item elsewhere, so please be aware that we may cancel your order depending on the timing of your purchase. Thank you for your understanding.
