Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, its tapered points drawing the eye along the finger with quiet drama. This semi-set solitaire ring in 14K rose gold offers a delicate balance between presence and subtlety, designed to sit low and close for everyday grace.

The band’s gentle curve and polished finish ensure a comfortable fit, while the secure prong setting awaits your choice of an 8 x 4 mm marquise center stone. Crafted in Williamsburg, each piece undergoes meticulous hand-finishing and inspection to meet exacting standards without excess height or bulk.

Choosing a lab-grown diamond here means embracing clarity and brilliance with a lighter environmental footprint, reflecting a modern commitment to ethical jewelry. The slender rose gold shank complements the marquise’s elongated form, flattering a range of hand shapes and lending itself well to stacking or solo wear.

Resizing is straightforward, handled in-studio to maintain the ring’s integrity and comfort. Whether you visit us in Williamsburg or design online, this mounting invites a personal connection to a piece made for daily life.
