Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with quiet drama. This three-stone semi-set ring foundation awaits your choice of a 10 x 5 mm marquise center, designed to showcase the stone’s signature brilliance and graceful elongation.

Crafted from solid 18K yellow gold, the band is shaped for comfort with a subtle taper that balances presence and wearability. Each prong is hand-formed in our Williamsburg studio, ensuring a secure yet delicate hold that lets light flood the diamond’s facets. The low-profile setting keeps the ring close to the hand, ideal for everyday wear without catching.

Our commitment to ethical jewelry is reflected in the option for a lab-grown marquise diamond, offering clarity and sparkle with a smaller environmental footprint.

The ring’s design suits those who appreciate refined geometry and a statement that’s both elegant and versatile. Its slender band pairs well with stacking rings or stands confidently alone. The semi-set style invites you to select a center stone that resonates personally, whether a classic white or a subtle fancy hue.

Should you need resizing or prefer a custom finish, our Brooklyn studio offers personalized consultations to ensure your ring fits seamlessly into your life.
