When light catches the elongated facets of this marquise-cut diamond, it traces a delicate arc that seems to extend the hand’s natural elegance. The 9 by 4.5 mm stone is securely nestled in a low-profile platinum setting, designed for everyday grace without catching or lifting.

Crafted in Williamsburg, this engagement ring balances technical precision with subtle artistry: the platinum band is polished to a satin finish for a soft touch against the skin, while the accent stones add a quiet shimmer that complements the center without overwhelming it. The setting’s streamlined silhouette ensures comfort fit and glove-friendly wear, ideal for a life in motion.

Each diamond is lab-grown, offering a clarity and brilliance indistinguishable from mined stones, with a fraction of the environmental impact. This ethical choice reflects a commitment to sustainability without compromise on beauty or durability.

Its slender profile and refined shape suit hands that appreciate architectural lines and a confident yet understated statement. The ring pairs effortlessly with stacking bands or stands alone as a singular expression of intention.

Should you need a custom adjustment, resizing is handled in-house with care to maintain the integrity of the setting and stone alignment.
