Lab-Grown Diamond Engagement Ring

Light catches the sharp, architectural facets of the 9 x 9 mm Asscher diamond, casting a glassy, almost ethereal glow that feels both intimate and striking. This solitaire semi-set ring offers a poised foundation, inviting you to select a center stone that speaks to your personal story.

Crafted in a fixed two-tone combination of warm 18k rose and 18k rose and platinum and cool 18k rose and platinum, the band balances softness with strength. The low-profile setting ensures the ring sits comfortably against the finger, while the subtle contrast between metals highlights the diamond’s geometric clarity. Each piece is meticulously finished and inspected in our Williamsburg studio, where precision meets quiet artistry.

Our commitment to ethical jewelry is reflected in the use of lab-grown diamonds, chosen for their clarity and sustainability without compromise.

Designed for those who appreciate architectural elegance and understated romance, this ring suits slender to medium finger shapes and layers effortlessly with stackable bands. Its comfort fit and low profile make it ideal for daily wear, including glove-friendly occasions.
