All weights and measurements are estimated and approximate. Treatments for jadeite and other gemstones are assumed unless otherwise noted.
  • Pre-owned jewelry may contain minor markings/imperfections throughout.
  • While we represent items accurately on our site to the best of our ability, the color calibration of computer monitors can vary, causing colors to appear slightly different from one monitor to another. Due to this, please note that precise color representation of metal and gemstones is not always possible.
