Lab-Grown Diamond Engagement Ring

Under the soft glow of Williamsburg’s evening light, a cushion-cut diamond captures a quiet moment—its gentle facets reflecting a dance of warmth and clarity. This halo setting cradles the 10 x 10 mm center stone in a delicate frame of platinum, where every prong is meticulously shaped and polished by hand to enhance brilliance without excess height.

Crafted for daily wear, the low-profile band rests comfortably against the skin, its smooth finish inviting touch and ease beneath gloves or alongside stackable rings. The platinum’s cool weight balances the diamond’s soft vintage glow, marrying durability with refined elegance.

Each lab-grown diamond here embodies a commitment to sustainable luxury, offering exceptional clarity and sparkle with a lighter environmental footprint.

Designed for those who appreciate subtle romance and thoughtful craftsmanship, this ring complements a range of hand shapes and sizes, its halo amplifying the cushion’s glassy, elongated charm without overwhelming.

Should you need a custom fit, resizing is handled expertly in-studio, ensuring your ring feels as natural as the moment it represents.
