Lab-Grown Diamond Engagement Ring

Soft light filters through a 9 x 9 mm cushion-shaped diamond, its gentle facets catching the eye with a quiet glow. This semi-set engagement ring in warm 18K rose gold offers a modern-minimal silhouette, where structured clarity meets subtle accents along the band.

Crafted in Williamsburg, the ring’s low-profile setting ensures daily wearability without sacrificing presence. The 18K rose gold band is hand-finished to a smooth comfort fit, its gentle curve inviting stacking or solo wear. Each accent stone is precisely set to enhance the cushion’s soft vintage glow while maintaining a clean, architectural feel.

Lab-grown for clarity and conscience, this ring reflects a commitment to sustainable luxury without compromise. Its semi-set design allows you to select a center stone that perfectly matches your vision, making the piece uniquely yours.

Ideal for those who appreciate refined geometry and a warm metal tone, this ring complements slender to medium finger shapes and slips easily under gloves or daily accessories. Resizing is available to ensure a tailored fit.
