Iridescent. Hand carved trochus shell, antique gold ring, adjustable 7-9. Ring is cast in USA from imported lead-free pewter, then plated with 24k gold. A secondary process of oxidization provides the aged look to the metals. Findings have been tested with Mutual Cornell and have certification that they have passed the EU Standards for lead and nickel release. Given the uniqueness of natural gemstones and handmade beads, and availability, some variation may occur and will be as close as possible to what is pictured.
