diamond tester?

[nyquestioner]

My grandmother has recently been in the habit of giving me some of her jewelry. She has real and costume pieces all mixed up and there's a few where I'm not sure what's what. Is there an inexpensive diamond tester I could buy on amazon to do a quick sort before I bring things in to a real appraiser?
Thank you.

Yes, its called Diamond Selector II.
There are many sellers out there, most in China.
I searched for one that had free shipping on Amazon.
It cost me about $15.00. I buy alot of jewelry from estate sales, and it helps so much. There are many others out there that cost so much more, but this one serves my purposes and it works great.
