Why Gold Kings recommends it

We would consider the PDMT-A for a jewelry inspection routine that already includes further checks. The handheld format, low-battery indication and metal-contact warning help support a consistent first screening step. The main buying question is whether thermal screening answers the question you need to investigate.

Features and specifications

  • Thermal-conductivity screening.
  • Metal-contact alert.
  • Low-battery indication.

Gold Kings buying advice

Practice the manufacturer’s probe technique and take care around metal settings. A thermal response alone does not reliably distinguish every simulant, including moissanite, and cannot establish natural versus laboratory-grown origin. Use the result to decide what further testing is needed, not as a grade or appraisal.
