Lab-Grown Diamond Engagement Ring
Imagine the subtle elongation of a marquise diamond catching light with every turn of the hand—its tapered points lending a refined drama that feels both bold and graceful. This semi-set halo engagement ring in platinum offers a secure, low-profile foundation designed to showcase a 12 x 6 mm marquise center stone, framed by a delicate halo that enhances brilliance without adding bulk.
Crafted in our Williamsburg studio, the platinum band is polished to a smooth finish, engineered for daily wear with a comfort fit that sits close to the finger. The halo setting balances sparkle and practicality, keeping the profile slim enough to slip easily under gloves or stack alongside other bands.
Each ring begins with a lab-grown diamond, chosen for its clarity and ethical origin, reflecting our commitment to sustainability without compromise. The semi-set design invites you to select a center stone that speaks to your personal vision, while the mounting is precisely calibrated to secure it with minimal elevation.
Ideal for those who appreciate architectural elegance paired with everyday functionality, this ring suits slender to medium finger shapes, emphasizing length and refinement. Resizing is available to ensure a tailored fit that feels effortless.
