Lab-Grown Diamond Engagement Ring

Under the soft glow of Williamsburg’s afternoon light, a 12 x 12 mm cushion-shaped diamond begins to whisper its story—an inviting blend of vintage warmth and modern clarity. This semi-set halo ring foundation, crafted from 18K palladium white gold, offers a cool, durable canvas for your chosen center stone, its broad shoulders gently curving to frame the gem with artisan precision.

The halo setting is designed with meticulous hand-finishing, each prong shaped to balance security and subtlety, allowing light to dance freely across the diamond’s softly rounded facets. The palladium alloy lends a luminous white sheen that resists tarnish, while the low-profile mounting ensures daily comfort and ease beneath gloves or alongside stackable bands.

Our commitment to ethical jewelry is reflected in the choice of lab-grown diamonds, combining exceptional clarity with a reduced environmental footprint.

This ring suits those who appreciate a blend of classic form and contemporary wearability—its generous cushion shape elongates the finger, while the halo setting adds a refined glow without overwhelming the hand. The semi-set design invites personal expression, letting you select a center stone that resonates with your vision.
