Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette across the hand. This three-stone semi-set ring frames a 9 x 4.5 mm marquise center with two delicate side stones, each carefully positioned to enhance its architectural grace.

Crafted from 18K white gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit that sits low against the finger, ideal for everyday wear. The setting’s artisan finish reveals subtle handwork in the prongs, securing the stones while allowing light to flood the facets for lively brilliance.

Each diamond is lab-grown, offering clarity and sparkle with a smaller environmental footprint, reflecting a commitment to ethical jewelry without compromise.

This ring suits those who appreciate a bold yet refined profile—its slender marquise shape elongates the finger, while the three-stone design adds narrative and balance. Its low-profile setting pairs seamlessly with stacking bands or alone as a statement piece.

Should you wish to adjust the fit, resizing is available to ensure comfort and longevity without disrupting the ring’s clean lines.
