Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise diamond, casting a delicate, tapered glow that seems to stretch beyond the finger. This semi-set solitaire ring offers a refined foundation crafted from 14K white gold, its cool sheen a subtle contrast to the warm blush of rose gold accents, finished by hand in our Williamsburg studio.

The band’s slender profile and smooth polish ensure a comfortable fit, designed to sit low for everyday wear without sacrificing presence. Each prong is meticulously shaped to cradle a 9 x 4.5 mm marquise stone securely while allowing maximum light to animate the diamond’s signature brilliance.

Our commitment to ethical jewelry shines through the use of a lab-grown diamond, chosen for its clarity and sustainability, reflecting a modern approach to luxury with a lighter environmental footprint.

This ring suits those who appreciate architectural elegance paired with artisan craftsmanship—its silhouette elongates the finger gracefully and pairs effortlessly with stackable bands or a wedding band. The semi-set design invites you to select a center stone that speaks personally, making it a truly bespoke expression.

Resizing is available to ensure a perfect fit, with care instructions provided to maintain the metal’s luster and the diamond’s sparkle over time.
