JUNK!!!
This thing is absolute junk! I tested a diamond three different times, used the same stone each time, and it gave me three different readings each time. I've tested sapphires and emeralds, and sometimes it tells me that the stone is a sapphire, and other times it told me it was something else.Pure junk. Plain and simple.
