Lab-Grown Diamond Engagement Ring

Imagine the gentle glow of a 7 x 7 mm cushion-cut diamond poised to catch the light with its soft, vintage-inspired facets—ready to become the centerpiece of your story. This semi-set engagement ring foundation in 18K rose gold offers a warm, subtle contrast to the diamond’s glassy brilliance, designed with a low-profile setting that sits close to the finger for everyday ease.

Crafted in Williamsburg, Brooklyn, the band is meticulously finished to a smooth comfort fit, ensuring it feels as natural as it looks. The mounting’s delicate accents frame the center stone without overpowering it, allowing for seamless stacking or solo wear. Each piece undergoes thorough inspection to meet exacting standards of durability and polish.

Our commitment to ethical jewelry is reflected in the choice of lab-grown diamonds, combining clarity and sustainability without compromise. This ring suits those who value refined craftsmanship and a design that adapts effortlessly to daily life, especially for hands that appreciate a balance of elegance and practicality.

Should you wish to adjust the fit, resizing is available to ensure your ring feels custom-made in every sense. Lead times are thoughtfully managed to maintain quality without unnecessary delay.
