Lab-Grown Diamond Engagement Ring

Sunlight catches the subtle sparkle of a 4.1 mm round diamond, poised to become the heart of your story. This semi-set solitaire ring foundation in 10K yellow gold offers a warm, classic canvas for your chosen center stone.

Crafted with a low-profile setting, the band sits close to the finger, ensuring comfort for everyday wear and ease beneath gloves or sleeves. The smooth finish and balanced weight reflect careful hand polishing and inspection in our Williamsburg studio.

Each diamond you select is lab-grown, embodying clarity and brilliance while aligning with a sustainable approach to fine jewelry.

The slender band suits a range of hand sizes and shapes, ideal for those seeking a minimalist yet confident statement. Its streamlined silhouette also pairs effortlessly with stacking bands or wedding rings.

Should you need resizing, our in-house experts adjust the band precisely to maintain its integrity and comfort.
