Understanding This Piece
About Sapphire
Sapphire is the second-hardest natural gemstone at 9 on the Mohs scale, making it durable enough for daily wear in engagement rings and bands. The classic deep blue is best-known, but sapphire occurs naturally in every color except red (which is classified as ruby) — including pink, yellow, peach, teal, and even color-changing varieties. Sapphire is the September birthstone and the traditional 45th-anniversary gem, and has been used in royal engagement rings for centuries (most famously Princess Diana's and Kate Middleton's).
About Platinum
Platinum is naturally white, hypoallergenic, and the densest precious metal used in fine jewelry — typically 95% pure (versus gold's 58.3% for 14K or 75% for 18K). It holds diamonds more securely than any gold alloy, never tarnishes, and develops a soft patina over years of wear that many buyers prize. Platinum costs roughly 1.5–2x equivalent 14K white gold but eliminates the rhodium-replating cycle and carries the strongest long-term durability of any setting metal. It is the standard for premium engagement rings and eternity bands.
