Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a subtle, tapered glow that draws the eye along the finger.

Set in a polished platinum halo mounting, this engagement ring balances architectural elegance with everyday practicality. The halo’s delicate pavé enhances the center stone’s brilliance without adding bulk, while the low-profile setting ensures comfort beneath gloves or sleeves. Each ring is meticulously finished and inspected in our Williamsburg studio, where precision meets quiet refinement.

Crafted with a lab-grown diamond, this piece reflects a commitment to ethical sourcing and environmental mindfulness without compromising on clarity or fire.

Designed for those who appreciate a sleek silhouette, the slender band and secure setting make it ideal for stacking or solo wear. The 8 x 4 mm marquise shape naturally elongates the finger, offering a graceful statement that suits both modern and classic tastes.

Should you need resizing, our in-house artisans provide careful adjustments to maintain the ring’s integrity and comfort.
