Lab-Grown Diamond Engagement Ring

When sunlight catches the sharp edges of a square diamond, it fractures into a quiet dance of light and shadow—an intimate moment captured in a five-stone embrace. This semi-set engagement ring offers a refined 18K white gold band, its cool surface polished to a soft glow that complements the geometric clarity of a 4 x 4 mm square center stone.

Crafted in Williamsburg, Brooklyn, the setting balances architectural precision with everyday wearability: the low-profile design ensures comfort beneath gloves or alongside stackable bands. Each prong is meticulously shaped and finished by hand, securing the stones while allowing their facets to breathe and sparkle freely.

Our commitment to ethical jewelry is reflected in the lab-grown diamond center, offering a clarity and brilliance indistinguishable from mined stones but with a lighter environmental footprint.

This ring suits those who appreciate modern geometry paired with subtle romance—its clean lines and five-stone rhythm echoing a quiet confidence on the hand. The semi-set style invites you to select a center diamond that speaks to your unique story.
