Lab-Grown Diamond Engagement Ring

Soft light filters through the gently rounded corners of a 5 x 5 mm cushion diamond, its subtle facets catching the eye like whispered promises. This three-stone semi-set engagement ring offers a foundation crafted from cool, enduring platinum, shaped and polished in our Williamsburg studio to a low-profile silhouette that rests comfortably against the skin.

Each prong is meticulously hand-finished to cradle your center stone securely while allowing maximum light to dance across its surface. The semi-set design invites you to select a lab-grown cushion diamond, chosen for its glassy, vintage-inspired glow and modern ethical clarity. The platinum band’s smooth comfort fit and modest height make it an ideal choice for daily wear, whether worn solo or stacked alongside other meaningful bands.

Lab-grown diamonds here reflect a commitment to sustainability without compromise on brilliance or integrity. This ring’s balanced proportions suit hands seeking a blend of classic romance and contemporary ease, with a setting low enough to slip under gloves and rings alike.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure your ring fits as naturally as a second skin. Lead times vary depending on stone selection, and we’re happy to guide you through every step.
