Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond, its tapered points drawing the eye along a delicate arc of rose gold. This three-stone engagement ring balances architectural grace with everyday ease, the 9 x 4.5 mm center stone set low to the finger for a sleek profile.

Crafted in warm 14K rose gold, the band’s subtle curvature and secure prong setting cradle the marquise and its flanking stones with precision. The comfort-fit shank ensures wearability from morning coffee to evening strolls, while expert finishing smooths every edge for a seamless feel.

Each diamond is lab-grown, offering clarity and brilliance without compromise, reflecting a commitment to sustainable, ethical jewelry practices.

Designed for those who appreciate refined geometry and understated elegance, this ring complements slender fingers and pairs effortlessly with stackable bands or wedding bands of similar scale.

Resizing is available to ensure a perfect fit, with careful attention to maintaining the ring’s balanced silhouette.
