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 float above the finger. This semi-set halo engagement ring in polished platinum frames a 9 x 4.5 mm marquise stone, inviting you to choose the center that speaks most intimately to your story.

Crafted with a low-profile halo setting, the ring balances architectural grace with everyday wearability. The platinum band is hand-finished to a smooth comfort fit, its subtle sheen complementing the diamond’s tapered drama without overwhelming the hand. Each detail is inspected in our Williamsburg studio to ensure a refined, enduring finish.

Our commitment to ethical jewelry is reflected in the lab-grown diamond option, offering clarity and sparkle with a lighter environmental footprint.

Designed for those who appreciate a slender, elegant silhouette, this ring suits hands that favor a refined statement—its halo enhances the marquise’s natural elongation while the low profile keeps it glove-friendly and stackable with other bands.

Should you wish to adjust the fit, resizing is available to ensure comfort without compromising the ring’s delicate balance.
