A Zambian emerald center flanked by lab-grown green diamonds and white diamonds in two-tone rhodium and 18K gold over sterling silver creates a fine colored stone ring with multiple rare elements working together. The Zambian emerald provides the named-provenance deep green at the center. The lab-grown green diamonds - colored diamonds created in the lab with the same boron process that creates natural colored diamonds - add genuine colored diamond quality that CZ or sapphire accents cannot replicate. The white diamonds provide the sparkle contrast that makes both greens appear richer. A ring where every element is a genuine gemstone story.
