Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to stretch the fingers gracefully. This 7 x 3.5 mm center stone is nestled within a halo of finely set pavé diamonds, amplifying its fiery brilliance against the warm glow of 14K rose gold.

Each ring is meticulously crafted in our Williamsburg studio, where the rose gold band is hand-finished to a smooth comfort fit, ensuring it sits low and secure for everyday wear. The halo setting balances sparkle with subtlety, designed to catch light without adding bulk, making it glove-friendly and ideal for stacking alongside wedding bands or delicate bracelets.

Our commitment to sustainability is reflected in the lab-grown diamond’s clarity and ethical origin, offering a conscious choice without compromising on radiance or craftsmanship.

This ring suits those who appreciate a blend of vintage-inspired drama and modern refinement, especially flattering on slender fingers where the marquise shape elongates the hand elegantly. The low-profile setting allows for ease of movement, perfect for a life lived fully.

Should you need a custom size, resizing is available with care to preserve the integrity of the halo and band.
