Sterling silver ring has a 14k yellow gold bezel and inlaid black jade, coral, and mother of pearl. Signet measures 12 mm by 12 mm and band tapers to 2 mm. This ring is unable to be resized. For longest lasting wear, all inlay jewelry should be removed for any strenuous activities (such as exercise, swimming, washing dishes, or showering) and in daily wear where it could get wet (like washing hands). Inlay stones can be porous and are much softer than many other jewelry materials.
