The enchanting, lush green of a 2.50-carat Colombian emerald takes command of this diamond halo engagement ring. Meticulously handcrafted of platinum with a rich yellow gold bezel embracing the gemstone and a fab filigree under-gallery. You will appreciate the attention to detail in this Art Deco-inspired masterpiece, created with a repurposed emerald and old-cut diamonds removed from a loved, but worn, 1920s heirloom. The vibrant green and silky smooth surface of the emerald contrasts wonderfully with 1 1/2 carats of icy diamond brilliance.
