A breathtaking Mid-Century two-piece diamond bridal set by C.K. Grantham Co., crafted in a stunning marriage of 14K yellow and white gold. This highly collectible 1950s–1960s set features a sculptural floral laurel-spray design—an iconic American jewelry motif of the Post-War Era when craftsmanship, romance, and gold weight still mattered. The center ring showcases a brilliant-cut diamond in a white-gold high-prong setting, wrapped in a sweeping spray of marquise-shaped diamond leaves. Paired with its original, thick solid 14K gold band, this set represents fine Mid-Century jewelry at its absolute finest.
This is investment-grade heirloom jewelry—authentic, era-correct, and fully original. Quiet luxury in its truest form.
