Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a subtle, tapered sparkle that draws the eye along the finger’s natural line. This semi-set solitaire ring offers a refined foundation for a 9 x 4.5 mm marquise stone, designed to sit low against the hand for everyday ease.

Crafted from 10K yellow gold, the band is shaped for comfort with a smooth interior and a secure prong setting that balances protection with light exposure. The low-profile mounting minimizes snagging, making it a practical choice for daily wear without sacrificing elegance.

Each piece is finished in our Williamsburg studio, where precision meets quiet durability, reflecting a commitment to sustainable luxury through lab-grown diamonds.

The slender band complements a variety of hand shapes and sizes, especially elongating fingers with its narrow, pointed center stone. Its solitaire style invites personal expression, whether worn alone or paired with stacking bands.

Should you need adjustments, resizing is handled expertly in-house to ensure a seamless fit.
