Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a subtle, tapered glow that draws the eye along the finger’s natural line. This three-stone semi-set engagement ring frames a 10 x 5 mm marquise center with two delicate side stones, each carefully positioned to enhance the stone’s signature pointed ends.

Crafted in 10K yellow gold, the band’s gentle curve and polished finish offer a warm contrast to the diamond’s crisp facets. The semi-set design invites you to select a center stone that reflects your personal vision, while the low-profile setting ensures everyday comfort and ease of wear. Each piece is hand-finished in our Williamsburg studio, where precision meets quiet artistry in every prong and contour.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both ethical sourcing and environmental mindfulness. This ring’s slender band and balanced proportions suit hands that appreciate refined detail and a subtle statement, ideal for stacking or wearing solo with grace.

Should you need resizing or prefer a different stone size, our Brooklyn studio accommodates custom adjustments with care and expertise. Typical lead times reflect our commitment to thoughtful craftsmanship rather than rushed production.
