Tiffany & Co. Classic Setting engagement ring in 18K rose gold with a platinum six-prong head, featuring a 1.22 carat round brilliant diamond, G color, SI1 clarity, excellent cut, polish, and symmetry. Size 5.25, weighing 3.1 grams. Recently professionally polished to showroom condition. Retail $18,000.

The two-tone construction is a deliberate choice — the platinum head keeps the diamond framed in white metal for maximum brightness, while the rose gold shank brings warmth to the overall look, a combination that's become increasingly popular for buyers who want color without sacrificing the diamond's clarity of white against the setting. At SI1, this stone is absolutely clean to the naked eye, with no visible inclusions even under close inspection — the kind of clarity grade that offers excellent value without any visual compromise. Triple excellent cut grades mean the diamond performs at the top of its category for brilliance. Comes complete with the original diamond certificate, a 2019 store receipt, and a retail/insurance evaluation.

Tiffany introduced the six-prong Classic Setting in 1886, and it remains the definitive engagement ring silhouette. This rose gold and platinum combination is one of the more contemporary ways Tiffany has adapted that century-old design, giving buyers the option of warmer metal tones without altering the setting's fundamental structure.

Condition: Excellent. Recently professionally polished to showroom condition. No scratches, no dents. Hallmarks clear and legible. Tiffany laser inscription on diamond intact.
