Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a delicate 6 x 3 mm frame. This semi-set halo ring foundation in warm 14K rose gold invites your choice of center stone, ready to be embraced by a handcrafted circle of pavé diamonds that amplify its vintage-inspired glow.

Each band is shaped and polished in our Williamsburg studio, where the soft blush of rose gold is carefully finished to a smooth comfort fit, designed for everyday wear without catching or pinching. The low-profile halo setting balances subtle sparkle with practical elegance, making it glove-friendly and ideal for stacking alongside a wedding band.

Our commitment to ethical jewelry is reflected in the option to select a lab-grown diamond, offering clarity and brilliance with a smaller environmental footprint. This ring suits those who appreciate refined craftsmanship and a silhouette that elongates the finger, lending a graceful, architectural presence.

Should you wish to adjust sizing, our in-studio artisans provide precise resizing to ensure a seamless fit. Typical lead times accommodate custom stone selection and setting, allowing for a personalized experience without rush.
