Part of our in-house EB line that incorporates rare vintage stones into modern, minimal mountings of our design. A black opal is bezel set in between a pair of Russian demantoid garnets-- among the rarest and most beautiful gemstones in the world. Demantoid garnets are a vivid lime green color and have a brilliance similar to diamond. Made in 18K yellow gold. Handmade in NYC. Note that both opals and demantoid are delicate stones, and this ring would not be especially well-suited to everyday wear.
