Lab-Grown Diamond Engagement Ring

Soft light catches the gentle curves of a 5 x 5 mm cushion diamond, its rounded corners and subtle facets inviting a quiet intimacy. This three-stone semi-set in cool platinum offers a delicate balance between presence and grace, framing the center stone with two smaller companions that enhance its warm glow.

Crafted in Williamsburg, the platinum band is polished to a satin finish that feels smooth against the skin, designed with a low-profile setting to sit comfortably beneath gloves or alongside other rings. Each prong is meticulously shaped to cradle the stone securely while allowing maximum light to pass through, revealing the diamond’s soft vintage shimmer.

Our diamonds are lab-grown, reflecting a commitment to ethical jewelry that reduces environmental impact without compromising brilliance or clarity.

This ring suits those who appreciate subtle romance and everyday elegance—its comfort fit and modest height make it ideal for stacking or solo wear, especially on slender to medium fingers where the cushion shape elongates the hand gently.
