Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a pointed grace that draws the eye along the finger. This semi-set three-stone engagement ring foundation pairs a 10 x 5 mm marquise center with two delicate side stones, designed to frame the centerpiece with quiet elegance.

Crafted in 14K white gold, the band offers a cool, luminous backdrop, while the rose gold accents warm the setting’s edges, creating a gentle contrast that enhances the diamond’s brilliance. The artisan finish is smooth to the touch, with a low-profile setting that sits comfortably for everyday wear and slips easily beneath gloves or sleeves.

Each ring is hand-finished in our Williamsburg studio, where precision meets thoughtful design—ensuring the prongs cradle your stone securely without excess height or bulk. The semi-set style invites you to select a lab-grown diamond of your choice, marrying personal meaning with ethical clarity.

Lab-grown diamonds bring a responsible sparkle, reducing environmental impact while maintaining the clarity and fire of mined stones. This ring’s shape and size suit hands that appreciate a statement with refined geometry, and the three-stone layout offers balance for stacking or solo wear.

Should you need resizing or adjustments, our Brooklyn studio provides attentive care to ensure your ring fits as naturally as a second skin. Typical lead times reflect our commitment to craftsmanship, with each piece made to order.
