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 halo engagement ring foundation in 18K yellow gold frames a generous 15 x 7.5 mm center stone with a delicate halo setting, designed to amplify brilliance while maintaining a graceful profile.
Crafted with meticulous attention in our Williamsburg studio, the band’s warm yellow gold is hand-polished to a soft luster, offering a smooth, comfortable fit that rests lightly on the finger. The halo setting is engineered to enhance sparkle without adding bulk, making it a refined choice for daily wear and layering with other bands.
Each lab-grown diamond reflects our commitment to ethical sourcing and sustainability, providing clarity and fire without compromise. The marquise shape’s distinctive, elongated form visually lengthens the hand, lending an elegant, vintage-inspired drama that suits those who appreciate subtle statement jewelry.
Designed for adaptability, this semi-set allows you to select a center stone that matches your vision, with resizing and finishing tailored in-studio to ensure a perfect fit. The low-profile setting pairs well with gloves and complements active lifestyles.
