Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that seems to stretch beyond the hand. This semi-set engagement ring offers a refined foundation in 18K yellow gold, designed to cradle a 6 x 3.5 mm marquise stone with precision and grace.

The band’s clean lines and subtle accents emphasize the diamond’s architectural shape, while the low-profile setting ensures everyday comfort and ease of wear. Each curve is meticulously finished in our Williamsburg studio, where expert hands polish and inspect every detail to a quiet brilliance.

Crafted with a lab-grown diamond in mind, this ring reflects a commitment to ethical jewelry—minimizing environmental impact without compromising on clarity or fire. The warm glow of yellow gold complements the marquise’s dramatic taper, making it a striking choice for those who appreciate modern minimalism with structural clarity.

Its slender band and modest height make it ideal for stacking or pairing with a wedding band, while the semi-set design invites you to select a center stone that speaks to your personal story. Resizing is available to ensure a seamless fit.
