Lab-Grown Diamond Engagement Ring

Light catches the marquise diamond’s elongated silhouette, casting a delicate sparkle that seems to stretch beyond the finger’s curve. This semi-set solitaire ring offers a refined foundation in 14K white gold, designed to cradle a 6 x 3 mm marquise stone with a subtle, low-profile setting that balances presence and everyday ease.

Each band is meticulously crafted in our Williamsburg studio, polished to a satin-smooth finish that feels weightless against the skin. The prongs are shaped to secure the pointed ends of the marquise, protecting its unique form while allowing maximum light to animate the stone’s facets.

Our commitment to lab-grown diamonds ensures clarity and brilliance without compromise, reflecting a modern approach to ethical jewelry that honors both beauty and sustainability.

Ideal for those who appreciate a ring that elongates the hand with architectural grace, this solitaire mounting suits slender to medium finger sizes and pairs effortlessly with stacking bands or a wedding band. Its comfort fit and low profile make it glove-friendly and perfect for daily wear.

Should you wish to adjust the fit, resizing is available with care to preserve the ring’s clean lines and structural integrity.
