Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set halo ring foundation in 18K white gold frames a 7 x 3.5 mm marquise stone, designed to amplify the gem’s signature brilliance and graceful shape.

Each band is meticulously crafted in our Williamsburg studio, where the cool sheen of white gold is hand-finished to a smooth comfort fit. The low-profile halo setting balances sparkle with everyday wearability, ensuring the ring sits close to the hand without catching. Our artisan approach includes precise prong work and a polished finish that invites daily touch.

Choosing a lab-grown diamond for the center stone means clarity and light without compromise, reflecting a commitment to sustainable, ethical jewelry practices.

This ring suits those who appreciate architectural elegance with a hint of vintage-inspired flair. Its slender profile complements slender to medium finger sizes and layers beautifully with stackable bands or wedding rings.

Should you wish to adjust sizing or explore custom stone options, our Brooklyn studio offers personalized consultations with thoughtful timelines.
