Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette across the hand. This three-stone semi-set engagement ring in 14K yellow gold frames a 7 x 3.5 mm marquise center with two gently tapered side stones, creating a balanced yet striking profile.

Crafted with a low-profile setting, the band sits close to the finger for everyday comfort and ease under gloves or rings stacked alongside. The warm glow of 14K yellow gold is polished to a satin finish, enhancing the metal’s natural luster without overwhelming the diamond’s sharp geometry. Each prong is precisely aligned to secure the marquise shape while minimizing metal visibility, allowing light to flood the stone’s facets.

Our diamonds are lab-grown, offering clarity and brilliance with a smaller environmental footprint. This ring’s design suits those who appreciate architectural elegance paired with practical wearability—ideal for hands that favor slender, elongated shapes or for anyone seeking a refined yet resilient engagement piece.
