Sunlight catches the elongated points of the marquise diamond, casting a slender, dramatic silhouette that seems to dance with every movement. This 9 x 4.5 mm gem is nestled securely in a platinum setting, its cool, silvery sheen a perfect complement to the stone’s fiery brilliance.

Handcrafted in our Williamsburg studio, the ring features delicate accent stones that frame the center with subtle sparkle, enhancing the marquise’s tapered drama without overwhelming its architectural grace. The platinum band is polished to a smooth finish, designed with a low-profile setting that sits comfortably for daily wear and slips easily beneath gloves or sleeves.

Each ring undergoes meticulous inspection to ensure the prongs hold the diamond firmly while maintaining an elegant, refined silhouette. The choice of lab-grown diamond reflects a commitment to ethical sourcing and sustainability, offering clarity and beauty without compromise.

Its slender shape and balanced proportions suit hands that appreciate a statement piece with refined understatement, ideal for stacking with complementary bands or worn solo as a distinctive emblem of commitment.
