Examination – Comparison Plate Large version




A Lexan 3.88″ x 2.2″ clear plate which allows the user to place one or two diamonds so that the stones are secure and steady while using the ASET or Ideal-Scope to examine their cut quality or to compare the light return and cut quality of two competing diamonds.  You might spend less time looking for a stone which popped out of your tweezers.  Retailers can use this across the counter to set up two diamonds and let the customer readily view and compare them.  Consumers find this device less of a challenge than handling and steadying a tweezers.  This plate is thick enough to safely block transmission of UV light when used in gemological testing.  Our smaller plate, 2″ x 2″ is not as thick.


This plate allows illumination from behind with your Smart Phone screen.  This small part is durable and prevents UV light transmission.


A smart phone App, such as Screen-Light, will work with this plate.   You can also use a white screen video available on YouTube.
