Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that dances with quiet confidence. This three-stone semi-set engagement ring in 10K yellow gold frames a 9 x 4.5 mm marquise center, its pointed ends drawing the eye along a sleek, architectural line.

Crafted with precision in Williamsburg, Brooklyn, the band’s smooth finish and low-profile setting ensure a comfortable fit for daily wear. The three-stone arrangement balances modern minimalism with structural clarity, allowing light to pass freely beneath the center stone for enhanced brilliance.

Each ring is thoughtfully designed with lab-grown diamonds, reflecting a commitment to ethical jewelry and sustainability without compromise on clarity or fire. The warm yellow gold complements the marquise’s glassy elegance, creating a harmonious contrast that suits those who appreciate refined geometry and subtle drama.

Ideal for hands that favor elongated shapes, this ring pairs effortlessly with stackable bands or stands alone as a statement of quiet strength. Its low profile makes it glove-friendly and unobtrusive, perfect for everyday life.

Resizing is available to ensure a perfect fit, with careful hand-finishing to maintain the ring’s sleek silhouette. Lead times are tailored to your custom design process, inviting collaboration at your pace.
