Lab-Grown Diamond Engagement Ring
Imagine the quiet confidence of a round diamond poised to catch light with every subtle movement. This semi-set platinum band awaits your choice of an 8.2 mm center stone, designed to showcase the classic brilliance of a round cut without excess height.
Crafted in platinum for enduring strength and a cool, smooth feel against the skin, the mounting features a low-profile setting that sits close to the finger, minimizing snagging and maximizing comfort for daily wear. The precise accents along the band add refined sparkle while maintaining a streamlined silhouette.
Each piece is carefully finished and inspected in our Williamsburg studio, reflecting a commitment to meticulous craftsmanship and thoughtful design. The lab-grown diamond option ensures clarity and ethical sourcing without compromise.
This ring suits those who value understated elegance and practicality—its comfort fit and low profile make it ideal for stacking or pairing with a wedding band. The semi-set style offers flexibility, allowing you to select a center stone that resonates personally.
Resizing is straightforward and handled in-house, ensuring your ring fits perfectly as your story unfolds.
