Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp corners of a 9 x 9 mm Asscher diamond, its step-cut facets unfolding like an architectural reverie. This semi-set solitaire ring offers a poised foundation, crafted in warm 10K yellow gold that embraces the stone’s geometric clarity with quiet strength.

The band’s smooth finish and moderate width ensure a comfortable fit for daily wear, while the low-profile setting keeps the silhouette sleek and glove-friendly. Each piece is meticulously hand-finished in our Williamsburg studio, where precision meets thoughtful design.

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

Ideal for those who appreciate modern geometry paired with classic warmth, this solitaire setting invites your personal choice of center stone to complete a ring that balances boldness with subtlety.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio offers attentive care to ensure your ring fits seamlessly.
