Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of an 8 x 8 mm square diamond, its facets unfolding like a quiet architectural poem across the hand. This five-stone semi-set engagement ring offers a foundation to showcase your chosen center stone, framed by a delicate row of smaller diamonds that catch light with subtle brilliance.

Crafted in 18K yellow gold, the band balances warmth and strength, its smooth finish designed for everyday wear. The setting sits low enough to slip comfortably beneath gloves or stack alongside wedding bands without catching, while the precise prongs secure your stone with refined minimalism.

Each piece is thoughtfully made in our Williamsburg studio, where lab-grown diamonds are selected for clarity and ethical provenance, reflecting a commitment to sustainability without compromise.

This ring suits those who appreciate architectural geometry softened by the gentle glow of yellow gold—ideal for hands that favor a bold yet wearable statement. The semi-set design invites personal choice, allowing your center diamond to become the heart of a bespoke story.

Resizing is available to ensure a tailored fit, with careful finishing to maintain the band’s sleek profile.
