Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, luminous shadow that dances across the skin. This semi-set engagement ring foundation in warm 18K yellow gold invites your choice of an 8 x 4 mm marquise center, a shape known for its graceful taper and subtle drama.

Handcrafted in our Williamsburg studio, the band’s smooth, low-profile design ensures a comfortable fit for daily wear, while the solitaire setting’s delicate prongs cradle the stone with precision. Each piece is meticulously finished and inspected to balance elegance with durability, making it an intimate extension of your everyday life.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and brilliance with a lighter environmental footprint.

The slender band complements slender or average finger sizes and pairs effortlessly with stacking rings or a wedding band. Its modest height slips easily beneath gloves or sleeves, perfect for those who favor subtle sophistication.

Should you wish to adjust the band size, resizing is available to ensure a seamless fit without compromising the ring’s refined profile.
