Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the hand with subtle drama. This halo engagement ring, set in cool platinum, frames the 7 x 3.5 mm lab-grown marquise with a delicate circle of pavé stones, enhancing its signature brilliance without overwhelming the design.

Each ring is meticulously crafted in our Williamsburg studio, where the platinum band is hand-finished to a smooth comfort fit, ensuring it rests lightly for daily wear. The low-profile halo setting balances sparkle with practicality, designed to slip easily beneath gloves or stack alongside a wedding band.

Our commitment to ethical jewelry shines through the use of a lab-grown diamond, offering clarity and fire with a smaller environmental footprint. This choice reflects a modern approach to engagement rings, marrying beauty with responsibility.

Ideal for those who appreciate architectural elegance with a hint of vintage allure, the marquise shape elongates the finger, while the halo adds a whisper of glamour. The ring’s refined proportions suit a range of hand sizes, making it a versatile choice for everyday grace.
