Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it draws the eye along a graceful arc, evoking subtle drama and refined elegance. This semi-set halo engagement ring foundation in platinum offers a secure, low-profile setting designed to cradle a 7 x 3.5 mm marquise stone, balancing architectural poise with everyday comfort.

Crafted in Williamsburg, the platinum band is meticulously finished for a smooth feel against the skin, with a halo setting engineered to enhance brilliance while maintaining a sleek profile that slips easily beneath gloves or sleeves. The mounting’s precision ensures durability without bulk, ideal for daily wear.

Our commitment to sustainability is reflected in the use of a lab-grown diamond center, chosen for its clarity and ethical provenance.

This ring suits those who appreciate a statement piece that remains discreet in silhouette—perfect for slender fingers or as a stackable complement to other bands. The semi-set design invites you to select a marquise stone that resonates personally, with resizing available to ensure a tailored fit.
