Made by Presidium, the leading manufacturers of gem testing equipment.

There is downloadable software to connect it to your computer. The reading is then displayed along with a list of stones that match the reading, and you can click on each stone to see more information (constants). This saves time looking up charts.

Comes with a USB cable (connects to any computer/mobile device / USB-mains adaptor). 

Works with loose stones and also stones mounted in small items of jewellery.

USES:

- to confirm stones are as described by your supplier

- to show a customer the reading, when you already know what the stone is and just need to 'prove' it

- to sort parcels of stones to see which look 'interesting' and worthy of further investigation, and then...

...to narrow the possibilities down to a handful of stones (sometimes just 1 or 2) so that you can carry out further investigations.

QUESTIONS & ANSWERS

Ask a Question
  • hi will this machine be able to measure and show me the difference between moissanite and cvd diamond ? I have heard of cvd diamond coated moissanite too to circumvent other test methods. im a small player in this game so i have time to test each stone should a test machine like this help.

    The manufacturers have not tested the Prim II on CVD diamond-coated Moissanite so the best they can say is, "Maybe, but probably not".

  • can you use this for mounted stones

    No.

  • Please can I use this Digital refractometer by presidium ( Model prim 11) to test and know a real Rough Diamond from fake.

    No. The stone must have a perfectly polished perfectly flat surface to rest on the test-plate of the refractometer.
