Lab-Grown Sapphire Round Four-Prong Ring | Unisex | S925 Silver

Some designs endure because they are simply correct. Four prongs, a round stone, a clean band — the four-prong solitaire has been the standard for fine gemstone rings for over a century, and in deep blue sapphire, it remains exactly that.

Crafted in S925 Sterling Silver, this ring features a lab-grown sapphire in a round cut, held by four prongs in the most direct and considered way possible. The four-prong setting elevates the stone above the band, allowing light to enter from all angles and the sapphire’s deep blue to be seen in full. It is a setting that makes no attempt to distract from the stone — because the stone does not need it. Designed as a unisex piece, the proportions and finish work equally well across all wearers, making it a natural choice for couples, for personal wear, or for anyone who appreciates a ring that is defined by its stone rather than its setting. Available in a range of sizes to ensure the right fit.
