Sapphire & Lab Diamond Engagement Ring in 14K White Gold

Six sides, one unforgettable stone. This hexagon sapphire engagement ring centers a lab-grown sapphire in a rare violet shade — mystery and grace cut into clean geometric lines — then frames it with D/VVS1 lab-grown diamonds that catch light at every turn, all on a slender 1.7 mm band in solid white gold or platinum.

Geometry as a Statement

Round stones whisper; a hexagon speaks. The six crisp sides of this cut give the sapphire a bold, architectural silhouette that reads modern from across a room and celestial up close — a favorite of brides who love hexagon engagement rings and the wider world of fantasy-inspired engagement rings. The slender 1.7 mm band stays deliberately quiet so the stone’s luminous symmetry does the talking.

A Violet Sapphire, Grown Not Mined

The center stone is a lab-grown sapphire — genuine sapphire, real corundum, chemically identical to a mined stone and rated a hard Mohs 9 for confident everyday wear. Its soft violet shade is the unusual part: a color between twilight blue and amethyst purple that few engagement rings dare to wear. Prefer tradition? The same design is also available with a royal blue lab sapphire upon request. For more on unusual hues, our purple gemstones guide and our guide to sapphire engagement rings are both worth a read.

Real Diamonds, Responsibly Made

The accents encircling the sapphire are lab-grown diamonds graded D color and VVS1 clarity — real diamonds in every physical and chemical sense, simply grown above ground for a sustainable, ethical sparkle. They radiate light with every movement, creating the celestial glow this design is known for. Skeptical? Our explainer on whether lab-grown diamonds are real settles it, and our lab-grown diamond engagement rings show the stone in every style.

Solid White Gold or Platinum, Never Plated

Every ring is made in your choice of solid metal, so the color you see is permanent — real metal all the way through, never plated, and it will not turn your skin green. 10K white gold is the most durable and most affordable; 14K is our classic best-selling balance of resilience and richness; 18K offers the highest gold content for a warmer, more luxurious feel; and platinum is naturally white, noticeably denser, and hypoallergenic. Compare them in our 10K vs 14K vs 18K gold karat comparison guide. Other colors are available on request.
