Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of the 9 x 7 mm emerald-cut diamond, casting a glassy, architectural glow that seems to stretch time itself. Nestled within a delicate halo of smaller stones, this platinum ring balances bold geometry with a whisper of romance, its low-profile setting designed for everyday grace.

Each ring is meticulously crafted in our Williamsburg studio, where the platinum band is hand-finished to a smooth comfort fit, ensuring it rests lightly against the skin without catching. The halo setting enhances the diamond’s clarity and depth, while the secure prongs hold the stone firmly, inviting daily wear without hesitation.

Our commitment to sustainability is reflected in the lab-grown diamond’s exceptional clarity and ethical origin, offering brilliance without compromise. This ring suits those who appreciate architectural elegance paired with subtle sparkle—its slender band and low profile make it ideal for stacking or wearing solo with ease.

Should you need resizing, our in-studio artisans provide careful adjustments to maintain the ring’s integrity and comfort. Typical lead times reflect our dedication to handcrafting each piece with precision.
