Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that dances across the skin. This three-stone semi-set engagement ring in 14K yellow gold frames a 9 x 4.5 mm marquise center, its pointed ends drawing the eye along the finger with quiet elegance.

Handcrafted in Williamsburg, the band’s gentle curve supports the stones with a low-profile setting that balances presence and comfort. Each prong is meticulously finished to cradle the marquise securely while allowing light to flood its facets, revealing the gem’s signature tapered drama. The warm glow of yellow gold complements the diamond’s fire, creating a harmonious interplay of color and form.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both beauty and sustainability without compromise.

Designed for those who appreciate refined romance, this ring sits comfortably for daily wear and pairs effortlessly with stacking bands or a wedding band. Its slender profile slips easily beneath gloves or sleeves, making it a versatile choice for a modern life.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as natural as it looks.
