Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set halo engagement ring in warm 18K rose gold offers a delicate frame, ready to cradle a 12 x 6 mm marquise center stone of your choosing.

Handcrafted in our Williamsburg studio, the band features a finely detailed halo setting that enhances the diamond’s signature brilliance while maintaining a low profile for everyday wear. The rose gold’s subtle blush complements the stone’s fiery facets, polished to a satin finish that feels smooth against the skin.

Each ring reflects our commitment to ethical jewelry, showcasing lab-grown diamonds that combine clarity with sustainability. This design suits those who appreciate a refined silhouette that elongates the finger without overwhelming it, ideal for stacking or wearing solo with ease.

Should you need adjustments, resizing is handled with care to preserve the ring’s artisan integrity. We invite you to explore this semi-set halo in person at our Williamsburg workshop or begin your custom design journey online.
