Located in Lisbon, PT
Leitão & Irmão Mid-Century Emerald and Diamond Platinum Cocktail Ring, Portugal, 1950s–1960s, in Original Case. A striking mid-century cocktail ring by Leitão & Irmão, the historic Portuguese jeweller to the Royal House, masterfully blending vivid emeralds with a scintillating diamond ensemble. The design centres on a round brilliant-cut diamond with approximately 1.20 carats, framed by a pair of square emerald-cut emeralds of deep, saturated green, weighing an estimated 2.00 carats in total.
