Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it carves a striking, tapered brilliance 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 with a low-profile setting that nestles close to the hand for everyday ease.

Crafted from 18K white gold, the mounting is engineered for comfort and durability, with a secure prong arrangement that balances protection and visibility. The band’s smooth finish and subtle taper ensure it sits gracefully alongside other rings or alone, while the streamlined design minimizes snagging during daily wear.

Each piece reflects our commitment to ethical jewelry, featuring a lab-grown diamond option that delivers clarity and fire without compromise. This approach aligns with sustainable practices embraced by our Williamsburg studio.

Ideal for those who appreciate architectural elegance paired with practical wearability, this mounting suits slender to medium finger sizes and complements the marquise’s distinctive shape. Its modest profile makes it glove-friendly and stackable with complementary bands.

Should you wish to adjust sizing or explore custom finishes, our Brooklyn studio offers personalized consultations to ensure a precise fit and finish.
