Lab-Grown Diamond Engagement Ring

When light catches the sharp edges of a 4.5 x 4.5 mm square diamond, it reveals a crisp geometry that balances modernity with quiet strength. This semi-set halo engagement ring in 18K white gold offers a sculptural frame, where delicate pavé stones encircle the center, amplifying its architectural clarity without overwhelming the hand.

Each band is meticulously crafted in our Williamsburg studio, shaped for a comfortable fit that sits low against the finger to avoid snagging. The white gold is hand-polished to a soft sheen, enhancing the diamond’s icy brilliance while maintaining a subtle tactile warmth under the skin.

Our diamonds are lab-grown, ensuring a traceable origin with a smaller environmental footprint—an ethical choice that aligns with thoughtful craftsmanship.

This ring suits those who appreciate clean lines and a refined silhouette, ideal for daily wear and stacking with complementary bands. Its low-profile setting makes it glove-friendly and unobtrusive, perfect for an active lifestyle without sacrificing elegance.

Should you need a custom size, resizing is straightforward and handled with care by our in-house artisans.
