Among the highlights of the sale at Doyle New York on October 18 are two emerald and diamond brooches set with stones that display the prized deep green colour concentration of Colombian emeralds.
Emeralds of this quality are always highly sought-after, but the market has seldom been stronger.
From the collection of a family of Spanish descent is a c.1935 heartshaped brooch (right) signed Cartier Paris with French assay marks, set with a Colombian emerald of approximately 14.75 carats.
