Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This 10 x 5 mm center stone is cradled in a halo of delicate pavé, amplifying its sharp geometry with a subtle glow.

Crafted in warm 14K yellow gold, the ring’s low-profile setting balances modern minimalism with structural clarity. The smooth band offers a comfort fit, designed for everyday wear without sacrificing elegance. Each facet is meticulously inspected in our Williamsburg studio to ensure precise light performance and lasting polish.

Choosing a lab-grown diamond means embracing a sustainable approach to brilliance, with a clear conscience and exceptional clarity.

The marquise shape naturally elongates the finger, making this ring ideal for those who appreciate confident lines and architectural form. Its halo setting adds dimension while maintaining a sleek silhouette that pairs effortlessly with stacking bands or a wedding band.

Should you need a custom size, resizing is available to ensure a perfect fit without compromising the ring’s integrity.
