Presidium

Q: What is the best presidium model?

I have the colored stone estimator model and like it very well. The duo meter is good for follow-up testing of colored stones,also. The main thing to remember is that you have to make several tests to verify a gemstone properly, such as a refractometer, etc. Presidium is top of the line.

Q: is there one now with a moissanite tester?

Yes that will the presidium duo model we have it available starting at 349

Q: The red light won't stop flashing to indicate the tester is ready for calibration. What can I try to reset it?

As you stated, the Tester is ready for calibration. Please follow the calibration instructions in the little manual or go to the Presidium website. Good Luck!!!
