This refined elongated hexagon lab diamond engagement ring features a striking geometric design that blends modern elegance with timeless diamond brilliance. The centerpiece is a stunning 7 × 11 mm elongated hexagon diamond, a dramatic gemstone shape known for its architectural lines and contemporary aesthetic.
The elongated hexagon cut is often associated with kite cut or dagger shaped gemstones, creating a distinctive silhouette that immediately distinguishes this ring from traditional engagement ring styles.
The center diamond is complemented by a carefully designed chevron contour band, which frames the stone while adding additional sparkle through matching diamond accents. This V-shaped band enhances the geometry of the center stone and creates a graceful layered composition. Together the engagement ring and matching contour band form one of our most distinctive wedding ring sets for women.
At the center sits an IGI certified lab grown diamond graded D color and VVS1 clarity, offering exceptional brilliance and clarity equal to natural diamonds. The accent stones are also lab grown diamonds, ensuring uniform sparkle throughout the ring. You can learn how these stones are grown and certified in our complete guide to lab-grown diamonds.
Crafted in solid yellow gold — available in 10K, 14K, or 18K — the setting provides long-lasting durability while enhancing the brilliance of the diamonds. The rich gold tone creates a luxurious contrast against the crisp white sparkle of the diamonds.
This geometric diamond engagement ring is perfect for those seeking a bold yet elegant ring, and it sits among our favorite lab-grown diamond engagement rings for shoppers who want modern gemstone shapes paired with timeless fine jewelry craftsmanship.
Each ring is made to order, ensuring precise craftsmanship and careful stone setting.
Choose your gold: 10K, 14K, or 18K solid yellow gold
Both pieces in this set are made in the same solid yellow gold, and you can select your karat from the drop-down:
► 10K — the most durable and affordable option, with a slightly lighter gold tone.
► 14K — the classic balance of warm color and everyday durability, and our most popular choice.
► 18K — the highest gold content for the richest, deepest yellow hue.
Every option is genuine solid gold throughout — never plated — so the warm yellow color is permanent and won't fade, tarnish, or turn your skin green. If you'd like this design in white or rose gold instead, those colors are available on request. Not sure which karat is right for you? See our 10K vs 14K vs 18K gold karat comparison guide.
