Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow across the hand. This semi-set engagement ring invites you to select a center stone that commands attention with its 12 x 6 mm proportions—an elegant shape known for its tapered points and vintage allure.

Crafted from warm 14K rose gold, the band is shaped and finished in our Williamsburg studio with subtle artisan touches that reveal the hand of a skilled jeweler. The setting’s delicate accents frame the future center stone while maintaining a low profile, ensuring comfort for daily wear without sacrificing presence.

Each ring is designed around a lab-grown diamond, chosen for its clarity and ethical origin, reflecting a commitment to sustainability without compromise. The rose gold’s gentle blush complements the marquise’s dramatic form, creating a harmonious balance that suits slender to medium finger shapes.

Its slender band and modest height make this ring ideal for stacking or pairing with a wedding band, while the semi-set design offers flexibility to personalize your stone choice. Resizing is available to ensure a perfect fit, crafted with care in our Brooklyn workshop.
