Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a striking interplay of brilliance and shadow, evoking a sense of refined drama. This semi-set halo engagement ring foundation in polished platinum offers a secure, low-profile setting designed to showcase a 7 x 3.5 mm marquise center stone with architectural grace.

Crafted with precision in our Williamsburg studio, the platinum band balances durability with a smooth comfort fit, ensuring it sits close to the finger without catching. The halo setting is engineered to enhance the diamond’s lengthening effect while maintaining everyday wearability and glove-friendliness.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, combining clarity and sustainability without compromise.

Ideal for those who appreciate a sleek silhouette and subtle statement, this mounting suits slender fingers and pairs effortlessly with stackable bands or wedding rings of varied profiles.

Should you require resizing, our in-studio experts handle adjustments with care to preserve the integrity of the setting.
