Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a slender finger, crowned by a marquise diamond’s tapered brilliance catching light with every movement. This semi-set platinum solitaire offers a refined foundation for a 5 x 3 mm marquise center, its pointed ends drawing the eye along a sleek, architectural silhouette.

Crafted in platinum, the mounting balances strength with a low-profile design that sits close to the finger, minimizing snagging and maximizing comfort for daily wear. The prongs are precisely shaped to cradle the stone securely while allowing ample light to animate the diamond’s signature sparkle. Each piece is hand-finished and inspected in our Williamsburg studio to ensure exacting standards.

Choosing a lab-grown diamond for your center stone aligns with a commitment to ethical jewelry—reducing environmental impact without compromising on clarity or fire.

This solitaire setting suits those who appreciate clean lines and understated elegance, especially on slender to medium-width fingers. Its low profile makes it glove-friendly and ideal for stacking with complementary bands.

Should you need resizing, our in-studio experts handle adjustments with care to maintain the ring’s structural integrity and finish.
