Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful arc. This semi-set engagement ring frame awaits your choice of a 6 x 3.5 mm marquise center, designed to showcase the stone’s distinctive tapered drama with modern-minimal clarity.

Crafted in 14K yellow gold, the mounting features delicate accent settings that enhance the diamond’s structure without distraction. The band’s slender profile and smooth finish ensure a comfortable fit for daily wear, while the low-profile setting keeps the ring glove-friendly and stackable alongside other favorites.

Each piece is meticulously hand-finished in our Williamsburg studio, where precision meets quiet confidence in every curve and prong. The semi-set design offers flexibility, inviting you to select a lab-grown diamond that aligns with your vision and ethical values.

Lab-grown diamonds provide a sustainable alternative with the same optical brilliance and clarity as mined stones, reflecting a commitment to responsible luxury.

This ring suits those who appreciate architectural elegance paired with subtle accents—ideal for hands that favor elongated shapes and a refined, modern aesthetic.

Resizing is available to ensure a perfect fit, and our team is happy to guide you through care and customization options during your visit or online consultation.
