Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, luminous shadow that dances across the hand. This halo setting cradles a 9 by 4.5 mm lab-grown marquise, its pointed ends drawing the eye along a graceful arc of light.

Crafted in cool platinum, the band offers a subtle weight and a smooth comfort fit, designed for everyday wear without intrusion. The halo’s delicate pavé setting enhances the center stone’s brilliance, while the low-profile mounting keeps the ring close to the finger, ideal for stacking or glove-friendly occasions. Each piece is meticulously finished and inspected in our Williamsburg studio, where precision meets quiet artistry.

Our diamonds are sustainably grown, offering clarity and sparkle with a conscientious footprint. This ring suits those who appreciate refined drama—a shape that elongates the finger and carries a whisper of vintage allure without excess.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio welcomes you to a pressure-free consultation. Lead times are transparent, with every detail tailored to your rhythm.
