Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This three-stone semi-set ring in 10K white gold offers a delicate balance between bold geometry and romantic flow.

Crafted with a low-profile setting, the band’s smooth comfort fit ensures it rests naturally against the skin, ideal for daily wear. Each prong is hand-finished in our Williamsburg studio, securing the center stone while allowing maximum light to animate the diamond’s signature brilliance.

Our lab-grown diamonds provide the same clarity and fire as mined stones, with a fraction of the environmental impact—reflecting a quiet commitment to ethical jewelry.

The 7 x 3.5 mm marquise shape elongates the finger, lending an elegant, almost architectural presence without overwhelming smaller hands. Its three-stone design invites pairing with a slim wedding band or stacking with other favorites.

Should you need a custom fit, resizing is available to ensure the ring feels as personal as the moment it marks.
