Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow across the hand. This three-stone semi-set engagement ring in 18K rose gold frames a 9 x 4.5 mm marquise center with two delicate side stones, offering a modern-minimal expression of clarity and structure.

Crafted in Williamsburg, the band’s warm rose gold is hand-finished to a smooth, comfort fit that rests lightly yet securely. The low-profile setting keeps the stones close to the finger, ideal for daily wear and effortless stacking. Each prong is meticulously inspected to cradle the marquise’s tapered points without compromising its architectural elegance.

Choosing a lab-grown diamond means embracing a refined brilliance with a smaller environmental footprint, reflecting a quiet commitment to ethical jewelry.

This ring suits those who appreciate confident geometry and subtle sophistication, especially flattering on slender fingers where the marquise shape elongates the hand. Its semi-set design invites you to select a center stone that resonates personally, making the ring uniquely yours.

Resizing is available to ensure a perfect fit, with care instructions tailored to preserve the rose gold’s gentle glow and the diamond’s crisp facets.
