Diamond Tester Pen

Hey!

today I want to talk to you about my most recent purchase from Amazon. Today I got this diamond Tester Pen in my mail. With this tool you can test if diamonds are fake or real and you can also test other gemstones. I bought this device because my wifi loves shopping vintage and antique jewels. Often she buys from ebay shops but to be 100% sure we bought this. I can only recommend this!
