Lab-Grown Diamond Engagement Ring

In the quiet light of a Williamsburg morning, the elongated marquise diamond catches a subtle gleam, its tapered points drawing the eye along a delicate halo of pavé-set stones. This platinum engagement ring balances architectural drama with artisan precision, each facet polished to reveal the gem’s signature brilliance.

Handcrafted in our Brooklyn studio, the halo setting cradles the 6 x 3 mm marquise with a low-profile silhouette that rests comfortably against the finger. The platinum band is meticulously finished for a smooth, comfort fit, designed to wear effortlessly every day while showcasing the diamond’s graceful elongation.

Our commitment to ethical jewelry is reflected in the lab-grown diamond’s clarity and sustainability, offering a conscious choice without compromise on radiance or craftsmanship.

Ideal for those who appreciate a refined statement piece, this ring complements slender fingers and pairs beautifully with stacking bands or a wedding band of similar profile. Its secure setting and streamlined design make it glove-friendly and suited for daily wear.

Should you need a custom adjustment, resizing is available to ensure a perfect fit without disrupting the ring’s balance.
