Part of our in-house EB line which incorporates unusual vintage gemstones into modern, minimal mountings of our design. This ring has a pair of vintage gemstones, each purple, but reacting very differently with the light due to their make-up. A natural pinkish-purple amethyst is set next to an East-West oriented amethyst. In certain light, the tones match perfectly, while at other times the sapphire shifts noticeably more pink. Set in platinum with a 14K rose gold shank. Comes with an AGL certificate for the sapphire which states natural origin and evidence of heat-treatment (a common enhancement of sapphires that dates back to antiquity).
