Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of an oval diamond, casting a gentle glow that seems to stretch beyond the stone itself. This semi-set engagement ring foundation in warm 10K rose gold invites you to select a center stone up to 12 by 10 millimeters, offering a graceful silhouette that elongates the finger with subtle sophistication.

Handcrafted in our Williamsburg studio, the band’s soft, rounded edges ensure a comfort fit designed for everyday wear. The low-profile solitaire setting balances security with elegance, allowing light to dance freely across the diamond’s surface once set. Each piece is meticulously finished and inspected to meet exacting standards, reflecting the artisan’s touch in every detail.

Choosing a lab-grown diamond for this ring aligns with a commitment to ethical jewelry—minimizing environmental impact without compromising brilliance or clarity.

Its slender rose gold band complements a variety of hand shapes and sizes, making it an ideal base for those who appreciate refined, stackable designs or a singular statement. The semi-set nature means you can personalize the ring with a stone that perfectly matches your vision.
