Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it draws the eye along a graceful arc—an elegant whisper of vintage allure and modern edge. This semi-set halo ring foundation in platinum offers a sculptural frame designed to amplify a 10 x 5 mm marquise center stone, cradled by a delicate halo that enhances brilliance without overwhelming the finger.

Crafted in our Williamsburg studio, the platinum band is hand-finished to a satiny smoothness, balancing durability with a refined low profile that slips comfortably beneath gloves or alongside other stackable bands. The halo setting is engineered for daily wear, securing the stone while allowing light to dance freely through each facet.

Our commitment to lab-grown diamonds ensures clarity and sparkle with a lighter environmental footprint, reflecting a modern approach to ethical jewelry. This ring’s slender silhouette suits hands that appreciate subtle drama and architectural elegance, especially flattering on longer fingers or those seeking a distinctive shape beyond the classic round.

Should you wish to adjust the fit, resizing is available with care to preserve the integrity of the halo setting. The semi-set design invites you to select a marquise stone that resonates personally, making the final ring uniquely yours.
