Lab-Grown Diamond Engagement Ring

Imagine the gentle curve of an elongated oval diamond poised to catch light with every movement, its 12 by 10 mm surface offering a graceful, expansive glow. This semi-set solitaire mounting in warm 10K rose gold provides a refined foundation, crafted for a low-profile silhouette that slips comfortably beneath daily gloves and rings alike.

Hand-finished in our Williamsburg studio, the band’s subtle taper and smooth comfort fit ensure wearability without compromise. The rose gold’s soft blush tone complements the oval’s elegant shape, enhancing its natural warmth and elongating effect on the finger. The setting’s secure prongs are engineered for stability while maintaining a delicate presence.

Each piece embraces lab-grown clarity, reflecting a commitment to ethical jewelry that aligns with sustainable values without sacrificing brilliance or craftsmanship.

Designed for those who appreciate understated sophistication, this mounting suits an oval diamond of generous scale, ideal for hands seeking a statement that remains effortlessly wearable. Its low profile and balanced weight make it a natural choice for stacking or solo wear.

Should resizing be needed, our Brooklyn studio offers precise adjustments to ensure a perfect fit, with attentive care instructions provided to maintain the metal’s warm glow.
