Worked great for diamonds. You just have to read the instructions. It beeps differently if you touch metal than it would touching a diamond. I used it on multiple real and fake to confirm it worked. The instructions don't tell you the specifications for rubies and other gems, though.

The instructions are terrible; and this definitely DOES NOT indicate if my crystal stones are real or fake.Not happy.
