Diamond tester

[mtntrekr2]

I am going to purchase a diamond tester. I know several others on this forum have testers of their own. I was wondering what type is being used and if there are any better than others. I understand it is the same as purchasing a new md. everyone has their favorite. I have seen prices from $39 out of hong kong to several hundred.
I expect to probably pay somewhere around $225.
Thank you for any pointers

Joe,

Wise choice. Pay as much as you can afford. Be aware that a tester that only tests CZ vs Diamond is not going to check for Moissanite. Only the higher end tester will do Moissanite. And even then, it's no guarantee, because the thermal conductivity of diamond and Moissanite are very close. When you test, follow directions carefully, and perform more than one test before you pass judgement. Good Luck.

Excellent reply. I use a GemPro PRO-DTester model. Mine will also test for sapphires as well. Moissanite jewelry in a display case will be lighted by pinkish to orangish display light to give more of a diamond sparkle. When closely examined under maginification in normal daylight, the stone will have a very slight gray/gray-greenish tint to it. Practised examination is the key. Moissanite will fool even the experts at times. Further, more sophisticated testing is often required.
