Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye like whispered promises. This semi-set engagement ring foundation in warm 18K yellow gold invites your choice of a 6 x 3 mm marquise center, framed by a delicate halo that amplifies its graceful drama.

Handcrafted in our Williamsburg studio, the band’s smooth finish and subtle low profile ensure it rests comfortably for everyday wear. The halo setting, meticulously crafted, enhances the stone’s brilliance without overwhelming its distinctive shape, while the secure prongs cradle the diamond with precision.

Each ring begins with a lab-grown diamond, chosen for its clarity and ethical origin, reflecting our commitment to sustainability without compromise. The gentle warmth of yellow gold complements the marquise’s vintage-inspired elegance, making it a natural fit for those who appreciate refined romance and modern craftsmanship.

Designed to sit close to the finger, this ring pairs effortlessly with wedding bands or stackable rings, offering versatility for evolving styles. Its slender profile also makes it glove-friendly, ideal for daily life in Brooklyn’s changing seasons.
