Getting the exact name of the stones now leaving to guess
The presidium instrument gemstones tester is a good product. It would have been great if there where actual light to indicate the name of the exact stone instated of just a line with more the one name leaving you to guess what exactly it's.

Good when working correctly.
I like the variation this tester has for identifying various gems . However , I find the pen has been extremely finicky and I can hardly have it calibrate up to the Cal indicator level without constantly cleaning and wiping down the cal glass and pen tip. I may have received a faulty pen as it has play back and forth ?
