For those who love the San Juan Mountain Band , we have created the Tapered Mountain Ring. Also representing the San Juan range, this tapered design has been described as "lighter" and "more feminine." Here, we have added a layer of 18k yellow gold sheet to the outer mountains. Set into the mountains is a CZ in a solid sterling silver bezel. We use the CZ for its affordable beauty but any birthstone can be substituted. The mountains are carved by hand meaning that no two or identical. Solid sterling silver with 18k yellow gold. If a diamond is required, please contact us.
