Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of an 8 x 4 mm marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set halo ring foundation in 14K white gold is crafted with meticulous artisan precision in our Williamsburg studio, where each prong is hand-shaped to cradle your chosen center stone securely while maintaining a low-profile silhouette.

The band’s smooth finish and balanced weight offer a comfortable fit for daily wear, designed to complement the marquise’s graceful geometry without overwhelming it. The halo setting, ready to embrace your center diamond, adds a delicate frame that enhances brilliance and presence without bulk.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, combining clarity and sustainability in every piece.

This ring suits those who appreciate refined craftsmanship and a design that elongates the hand, ideal for stacking or wearing solo with ease. Its low-profile setting slips effortlessly under gloves or sleeves, making it a versatile choice for everyday elegance.

Should you need resizing, our in-house experts ensure a precise adjustment without compromising the ring’s integrity or comfort.
