Lab-Grown Diamond Engagement Ring

The elongated silhouette of the marquise diamond, measuring 8 by 4 millimeters, draws the eye with its tapered points and graceful drama. This semi-set solitaire ring in 14K rose gold offers a delicate warmth that complements the stone’s sharp geometry without overwhelming it.

Crafted with a low-profile setting, the mounting ensures the diamond sits close to the finger, enhancing comfort for daily wear while maintaining secure prong placement. The smooth band curves gently, designed to balance the stone’s presence without bulk, making it an ideal choice for stacking or pairing with a wedding band.

Each piece is meticulously finished in our Williamsburg studio, where expert jewelers inspect every detail to meet exacting standards. The rose gold’s subtle blush is polished to a soft sheen, creating a tactile contrast to the diamond’s crisp facets.

Choosing a lab-grown marquise diamond aligns with a commitment to ethical jewelry, reducing environmental impact without compromising brilliance or clarity.

This solitaire mounting suits those who appreciate architectural elegance and a refined profile that slips easily under gloves or sleeves. Its versatile design accommodates a range of hand sizes, offering a balanced feel that’s neither too bold nor delicate.
