Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its pointed ends drawing the eye along a graceful arc that feels both intimate and expansive. This three-stone semi-set ring in 18K white gold frames a 9 x 4.5 mm marquise center with two delicate side stones, each carefully positioned to enhance the center’s slender elegance without overpowering it.

Crafted in Williamsburg, the band’s polished white gold offers a cool, luminous backdrop that complements the diamond’s sharp geometry. The low-profile setting ensures the ring sits comfortably for daily wear, while the smooth interior promises a gentle fit against the skin. Each piece is hand-finished and meticulously inspected to meet exacting standards of craftsmanship.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both ethical sourcing and environmental mindfulness.

Designed for those who appreciate refined romance and subtle drama, this ring suits slender fingers and pairs beautifully with stacking bands or a wedding band of similar profile. Its streamlined silhouette slips easily beneath gloves or sleeves, making it a versatile choice for everyday elegance.

Should you wish to adjust the size, resizing is available to ensure a perfect fit without compromising the ring’s structural integrity.
