Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of an oval diamond, casting a gentle glow that seems to stretch beyond the stone itself. This semi-set engagement ring invites your choice of a 12 x 10 mm oval center, a shape known for its graceful elongation that visually lengthens the finger with quiet elegance.

Crafted in warm 10K rose gold, the mounting balances softness with structure, designed to cradle your chosen diamond securely while maintaining a refined silhouette. The band’s smooth finish and subtle taper ensure comfort for everyday wear, while the solitaire setting highlights the stone’s natural brilliance without distraction.

Each piece is meticulously finished in our Williamsburg studio, where expert hands polish and inspect every curve and prong to meet exacting standards. The rose gold’s gentle blush complements the oval’s romantic profile, creating a harmonious foundation for your personal expression.

Our commitment to ethical jewelry is reflected in the option to pair this setting with a lab-grown diamond, offering clarity and sparkle with a lighter environmental footprint.

Ideal for those who appreciate a low-profile setting that slips easily beneath gloves or stacks seamlessly with wedding bands, this ring suits a variety of lifestyles and hand shapes, especially elongating shorter fingers with its oval centerpiece.
