Lab-Grown Diamond Engagement Ring

Soft light catches the gentle curves of a 5 x 5 mm cushion diamond, its rounded corners and subtle facets inviting quiet admiration. This solitaire semi-set ring offers a refined foundation, crafted in warm 18K rose gold with a low-profile white gold setting designed to keep the stone secure while maintaining everyday comfort.

Each band is hand-finished in our Williamsburg studio, polished to a smooth comfort fit that slides easily beneath gloves or alongside other stackable pieces. The setting’s subtle elevation balances visibility with practicality, ensuring the diamond’s vintage-inspired glow remains protected during daily wear.

Our diamonds are lab-grown, offering a clear, sustainable alternative without compromising brilliance or clarity. This ring suits those who appreciate understated elegance paired with technical assurance—a piece that feels as natural on the hand as it looks in the light.

Should you wish to adjust the fit, resizing is available with care to preserve the integrity of the setting. Lead times vary slightly depending on customization but are communicated transparently throughout the process.
