Very Rare 7 ct. Cat's Eye Emerald and Diamond 18K Ring

Write a Review

This is a rare cat's eye emerald. At over 7 carats, it is a statement ring with a rare twist:  a brilliant cat's eye. The emerald is a beautiful saturated green color with a beautifully defined cat's eye in direct lighting. We put this emerald in a setting we designed that has over 2 carats of colorless diamonds, all in 18K gold.

Larger, good color emeralds, which are already considered a rare gemstone, can have a rarer quality, displaying the optical effect of chatoyancy (the cat's eye effect) which is more commonly seen in other gemstones like chrysoberyl, sapphire, tourmaline, apatite, etc. The cat's eye emeralds are such a rare occurrence in nature that they are sought after by gemstone connoisseurs for their uniqueness. The chatoyancy, or cat’s eye, is the presence of numerous microscopic parallel narrow tubes that reflect light back to you from the surface of the stone when cut in a cabochon (no faceting).
