Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to stretch the fingers with quiet elegance. This semi-set engagement ring invites your choice of a 5 x 3 mm marquise center, cradled in a slender 18K white gold band that balances subtlety with refined presence.

Crafted in Williamsburg, the band’s low-profile setting ensures a comfortable fit for daily wear, its smooth finish reflecting the studio’s meticulous handwork. The solitaire design highlights the diamond’s unique shape—its graceful, tapered form offering a blend of vintage allure and modern geometry.

Each diamond is lab-grown, embodying a commitment to ethical jewelry that respects both clarity and conscience. The cool white gold complements the stone’s icy fire, creating a harmonious canvas for the marquise’s distinctive sparkle.

Ideal for those who appreciate understated sophistication, this ring sits close to the finger, making it glove-friendly and easy to stack with complementary bands. Its slender silhouette suits slender to medium finger sizes, enhancing the hand’s natural lines without overwhelming.

Should you wish to adjust the band size, resizing is handled with care in-studio to preserve the ring’s seamless profile. Typical lead times accommodate custom stone selection and finishing.
