This exquisite Art Deco ring features a beautiful 4.00-carat Colombian emerald. The rectangular step-cut gem sparkles with brilliance. The American Gemological Laboratories certifies this gem as Colombian in origin, as reflected in the emerald's deep "Old Mine" green hue, for which Colombian emeralds are prized. The remarkable stone is complemented by approximately 0.85 carats of white diamonds, artfully arranged with Art Deco flair. Set in platinum.
