Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points tracing a delicate arc that seems to cradle the hand. This semi-set halo engagement ring foundation in polished platinum offers a refined stage for a 7 x 3.5 mm marquise center, designed to amplify the stone’s dramatic sparkle while maintaining a graceful profile.

Crafted with precision in our Williamsburg studio, the platinum band is shaped for comfort and everyday wear, its subtle halo setting ready to embrace your chosen diamond with secure prongs that balance brilliance and protection. The low-profile mounting ensures ease beneath gloves or alongside stackable bands, making it a versatile companion for daily life.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that deliver clarity and fire without compromise. This approach honors sustainability while celebrating the unique beauty of engineered gems.

Ideal for those drawn to a statement ring that elongates the finger and captures light from every angle, this halo semi-set invites personalization and thoughtful pairing. The slender band and poised setting suit a range of hand sizes, offering a modern yet poetic expression of engagement.
