Lab-Grown Diamond Engagement Ring

Soft light catches the gentle curves of a 5 x 5 mm cushion diamond, its rounded corners inviting a quiet intimacy. This semi-set three-stone ring foundation in warm 18K rose gold offers a handcrafted frame that balances artisanal texture with refined polish.

Each band is shaped and finished in our Williamsburg studio, where the low-profile setting ensures the ring sits comfortably for daily wear without catching. The rose gold’s subtle glow complements the cushion’s vintage-inspired silhouette, while the three-stone design allows you to select side stones that enhance personal meaning.

Crafted exclusively with lab-grown diamonds, this piece reflects a commitment to ethical sourcing and sustainability without compromise on clarity or brilliance.

Its moderate width and smooth interior make it ideal for those who appreciate a ring that feels as natural as it looks—equally suited to stacking or wearing solo. The semi-set style invites customization, perfect for a bespoke engagement ring that fits your story.

Resizing is straightforward and handled with care in-studio, ensuring your ring maintains its structural integrity and finish.
