The event will take place at the Americas Society at 680 Park Avenue with online bidding at liveauctioneers.com.

The lot will feature a selection of exquisite emeralds including: La Gloria, which, at 887 carats, is one of the largest museum-quality emeralds in the world; Marcial de Gomar Star, the largest of only eleven star emeralds and a one-of-a-kind double-sided star emerald, as well as Tears of Fura, a beautiful matched pair of teardrop-shaped Muzo emeralds.

The auction will also see the largest collection of cut emeralds up for auction from the famous fleet of Spanish ships, Nuestra Señora de Atocha, including the single largest cut emerald recovered from that ship.

All of these items were privately owned and will be unveiled to the public for the very first time at the Marcial de Gomar Collection auction.
