Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc of brilliance that seems to dance with every movement. This semi-set platinum halo ring frames a 6 x 3 mm marquise center with a subtle circle of pavé stones, enhancing its tapered drama without overwhelming the hand.

Crafted in Williamsburg, the platinum band is polished to a soft sheen and designed with a low-profile setting that sits comfortably for daily wear. The halo’s precise pavé setting is inspected meticulously to ensure each tiny diamond nestles securely, creating a seamless shimmer that complements the center’s architectural shape.

Our commitment to ethical jewelry is reflected in the lab-grown diamond’s clarity and origin, offering a sustainable alternative without compromise on sparkle or integrity.

This ring suits those who appreciate a refined statement with a romantic edge—its slender silhouette elongates the finger while the halo adds a whisper of vintage allure. Its comfort fit and modest height make it ideal for stacking or wearing solo, and its glove-friendly design transitions effortlessly from studio to soirée.

Should you wish to adjust the fit, resizing is available with care to preserve the ring’s delicate balance. Typical lead times reflect the handcrafted nature of each piece.
