A stunning Art Deco Columbian emerald 18 karat white gold and platinum with baguette diamond ring. The estimated carat weight of the untreated step cut emerald is 3.47 carats that is set in a four-corner claw mount. This stylish Art Deco ring is typical of the period with baguette cut diamonds (0.42ct) channel set into the shoulders of the ring. A truly natural emerald with no oiling or enhancement to detract from the beauty of the stone in a classic Art Deco “stepped” shoulder setting. Columbian emeralds are the most desirable of all the locations to obtain rare emeralds.


The ring comes with a certificate from the UK Birmingham Assay Office dated December 2020 to attest that this is a natural untreated Beryl, Emerald from Columbia.
