This exquisite Art Deco Diamond Bar Brooch, circa 1920s, is meticulously handcrafted in lustrous platinum. Delicate and sophisticated, this diamond pin distinctively separates nine old mine-cut diamonds (totalling 3.30ct) by eight round brilliant-cut rubies (totalling 0.40ct), capturing the refined elegance of the early twentieth century. Framed by fine bezel settings and a uniform silhouette, the geometric elegance of the era is honoured in this timeless brooch.
