Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate dance of light that seems to whisper promises. This five-stone semi-set ring in warm 18K rose gold frames a 6 x 3 mm marquise center, its tapered points lending a graceful elongation to the finger.

Each setting is meticulously crafted in our Williamsburg studio, where the rose gold band is hand-finished to a soft, satin touch that wears comfortably against the skin. The low-profile mounting balances presence with everyday ease, designed to slip smoothly beneath gloves or stack alongside complementary bands.

Our lab-grown diamonds offer a clarity and brilliance that honors both beauty and conscience, reflecting a commitment to sustainable luxury. The five-stone arrangement enhances the marquise’s architectural charm, creating a subtle rhythm of light and shadow that feels intimate and refined.

Ideal for those who appreciate romantic detail without excess, this ring suits slender to medium finger shapes, its slender band emphasizing length and elegance. Resizing is available to ensure a tailored fit, crafted with care to maintain the integrity of the delicate setting.
