Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it casts a subtle, tapered glow that seems to stretch the hand with quiet elegance. This semi-set halo engagement ring foundation in polished platinum frames a 12 x 6 mm marquise center with delicate precision, designed to cradle your chosen stone in a low-profile setting that balances presence with everyday ease.

Crafted in Williamsburg, Brooklyn, the platinum band is meticulously finished for a smooth comfort fit, its halo setting offering a gentle sparkle that enhances the marquise’s signature pointed ends without overwhelming. The semi-set design invites you to select a lab-grown diamond of exceptional clarity and brilliance, ensuring a personal connection to the gem’s story and light.

Our commitment to ethical jewelry shines through the choice of lab-grown diamonds, reducing environmental impact while maintaining the highest standards of craftsmanship. The ring’s slender profile and secure setting make it ideal for daily wear, whether worn solo or stacked alongside other bands.
