Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a marquise diamond, casting a subtle, tapered glow that draws the eye along the finger’s natural line. This semi-set platinum mounting awaits your choice of a 10 x 5 mm marquise center, designed to cradle the stone securely with a low-profile setting that slips comfortably beneath gloves and daily wear.

Crafted in Williamsburg, the band’s polished platinum offers a cool, enduring foundation, shaped for a comfort fit that balances presence with ease. The prongs are precisely aligned to protect the delicate tips of the marquise, ensuring durability without bulk.

Each piece reflects our commitment to ethical jewelry: lab-grown diamonds provide clarity and brilliance with a smaller environmental footprint. This solitaire setting suits those who appreciate clean lines and a refined silhouette, ideal for stacking or wearing solo.

Resizing is straightforward, handled in-studio with care to maintain the ring’s structural integrity. Whether you visit us in Brooklyn or design online, this mounting invites a personal touch to your engagement story.
