A refined pair of authentic Art Deco drop earrings, exquisitely crafted in platinum and set with diamonds and polished black onyx. The design is quintessentially 1920s—geometric, symmetrical, and sharply elegant. Each earring is formed with a delicate line of graduated diamonds, suspending a circular onyx plaque framed by finely pavé-set diamonds. At the centre, a brilliant-cut diamond anchors the composition, while radiating diamond-set motifs add depth and architectural detail. The use of milgrain edging enhances the precision and craftsmanship typical of the period. The contrast of luminous diamonds against the deep black onyx creates a striking, graphic effect, while the articulated drops allow for fluid movement and light.
