Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of an oval diamond, casting a gentle glow that seems to stretch across the hand. This semi-set solitaire invites a fixed two-tone a 12 x 10 mm oval center stone, known for its graceful elongation and subtle vintage allure.

Crafted in a fixed two-tone combination of warm 18k rose and 18k rose and platinum and cool 18k rose and platinum, the six-prong setting balances modern minimalism with structural clarity. The lightweight band feels effortless on the finger, designed for daily wear with a low-profile silhouette that slips easily beneath gloves or alongside stackable rings.

Each piece is meticulously finished in our Williamsburg studio, where expert hands polish and inspect every contour to ensure a refined, comfortable fit. The lab-grown diamond option offers a brilliant, ethically sourced centerpiece with a smaller environmental footprint.

This ring suits those who appreciate confident simplicity and architectural elegance, especially flattering on slender fingers or as a standout solitaire. Resizing is available to ensure a perfect fit, with typical lead times reflecting our handcrafted approach.
