Colombian No-Treatment Emerald and Diamond Necklace by J. E. Caldwell - GIA

Upon being presented with a truly remarkable collection of rare and radiant gemstones: 7 old mine Colombian Muzo emeralds, the renowned American jeweler, J.E. Caldwell, created this thoroughly unique art piece of color and sparkle. (The GIA gemological report for emeralds states: Five (5) emeralds have no indication of treatment. Two (2) emeralds are minor clarity enhanced (F1). Colombia, origin.) The ultra-vibrant, richly saturated, crystalline bluish-green gems dangle below and between a glorious composition of European-cut, Swiss-cut and single-cut diamonds. At each end, a diamond-frosted Edwardian bow connects to a chain composed of small ribbed cylinders alternating in platinum and 14K gold (to match the diamond and emerald settings) and connected by an engraved clasp set with five twinkling diamonds. As famed jeweler Harry Winston said, "People will stare. Make it worth their while." This fabulous necklace will not disappoint. Total emerald weight - 10.00 carats; total diamond weight - 5.00 carats. Hand fabricated in platinum (emerald mountings are 18K yellow gold), circa early-20th century. Signed and numbered J.E.C. Co. It measures 15 1/2 inches.
