Lab-Grown Diamond Engagement Ring

Imagine the moment light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the length of your finger. This semi-set solitaire ring in 18K white gold offers a refined foundation for a 9 x 4.5 mm marquise center, its sleek prongs designed to showcase the stone’s dramatic shape while ensuring secure wear.

Each band is meticulously crafted in our Williamsburg studio, hand-finished to a smooth comfort fit that sits low against the hand for everyday ease. The polished white gold gleams softly, a cool contrast to the diamond’s fiery facets, while the minimalist setting keeps the focus on the stone’s architectural elegance.

Our commitment to sustainability is reflected in the lab-grown diamond option, offering clarity and brilliance with a lighter environmental footprint. This ring’s slender profile suits those who favor understated sophistication and pairs effortlessly with stacking bands or a wedding band.

Resizing is available to ensure a perfect fit, crafted with the same attention to detail as the original design. Whether you choose to visit our Brooklyn studio or begin your custom journey online, this mounting invites you to personalize a piece that resonates with your story.
