Dating back to the second or third decade of the twentieth century, this sleek and sophisticated Art Deco circle brooch was designed and meticulously handcrafted by the esteemed French jeweler, Boucheron. Designed as a hinged circular plaque, pavé-set with sparkling single-cut, old mine-cut and rose-cut diamonds, showcasing an enchanting cluster of sunshiney yellow old mine-cut diamonds paired with golden-brown, cognac brown and brown pink old mine-cut and marquise-cut diamonds. This exceptional jewel has an ingenious clip mechanism that allows the brooch to seemingly wrap around the edge of whatever the wearer clips it to. French assay marks, signed Boucheron Paris.
