Lab-Grown Diamond Engagement Ring

Imagine the soft glow of a 12 x 12 mm cushion diamond poised to catch the light with gentle, vintage-inspired warmth. This solitaire semi-set invites you to select the perfect center stone, framed by an 18K rose gold band that subtly warms the skin with its delicate hue.

Crafted in Williamsburg, Brooklyn, the band offers a low-profile silhouette designed for everyday wear—comfortably hugging the finger without excess height or bulk. The smooth finish and precise setting ensure the mounting supports the stone securely while remaining unobtrusive beneath gloves or stacked rings.

Each piece reflects a commitment to ethical jewelry, featuring lab-grown diamonds that deliver clarity and brilliance with a smaller environmental footprint. This ring’s design balances classic charm with modern sensibility, ideal for those who appreciate refined craftsmanship and conscious sourcing.

Its semi-set form allows you to customize the centerpiece, making it uniquely yours. The cushion shape’s softly rounded corners and faceted surface create a luminous, inviting sparkle that complements a variety of hand shapes and sizes.
