Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic shadow that dances with every movement. This 10 x 5 mm marquise lab-grown diamond, set in cool platinum, balances bold geometry with refined minimalism.

Crafted with precision, the platinum band offers a sleek, low-profile setting that hugs the finger comfortably, while subtle accent stones enhance the diamond’s sharp silhouette without distraction. Each ring is hand-finished in our Williamsburg studio, ensuring a smooth comfort fit and meticulous inspection before it leaves the bench.

Choosing a lab-grown diamond means embracing clarity and brilliance with a lighter environmental footprint, reflecting a modern commitment to ethical jewelry.

Designed for those who appreciate architectural elegance, this ring complements slender fingers and pairs effortlessly with stackable bands or a wedding band of similar refinement. Its low profile makes it glove-friendly and ideal for everyday wear.

Resizing is available to ensure a perfect fit, crafted carefully to maintain the integrity of the setting and stone alignment.
