To protect rare earth-mined gems during hand-setting, our master jeweler curates natural Vault stones in bench-safe shapes (like Rounds, Ovals, and Cushions) without sharp points. Since lab-grown diamonds don't carry the same replacement risks, we have no shape limits for those! If your heart is set on a natural Pear or Marquise, go ahead and select it—we'll just chat about protective setting styles (like V-prongs) during your consultation.
