Art Deco Platinum & 18kt Gold Ring with Colombian Emerald and Old Cut Diamonds

An exquisite Art Deco ring crafted circa 1920 in a combination of 18kt gold and platinum, featuring a striking geometric design typical of the period. The ring is centred with a natural Colombian emerald of approximately 0.50 carats, exhibiting vivid green colour and minor F2 oil treatment. It is flanked by two old European-cut diamonds of approximately 0.50 carats each, surrounded by twenty-five smaller accent diamonds totalling around 0.75 carats.

The diamonds display VS clarity and F–G colour, offering remarkable brilliance that complements the emerald’s deep hue. The openwork platinum setting and stepped shoulders enhance the ring’s architectural symmetry — a hallmark of fine Art Deco craftsmanship.
