Of the two different tools, research has shown that electrical conductivity diamond testers are much better than thermal conductivity diamond testers. They are higher in price, but much more accurate. Heat testers are much cheaper but their accuracy is not as high, so may not get as good results. Electricity-based diamond tester

By placing the needle-like tip on the surface of the rock in question, the tester will detect the heat or electrical transference of the stone and alert you with a little light or sound display as to the authenticity of your stone. Ta-da! But now you’re probably wondering: Are diamond testers actually reliable? Short answer: yes.

Likewise, you can test a genuine diamond in a ring, and have it buzz like it’s not a real stone.

Often times, store employees do not know how to identify counterfeit bills and rely on the simplest, least reliable counterfeit detection tool: the counterfeit pen. We'll discuss why counterfeit pens are not reliable and what are some valid alternatives.

It also is less hard, less brilliant (doesn’t refract light as well), more abundant and much cheaper. Because the heat dispersing qualities of a real diamond and moissanite are so similar, a regular diamond tester is not able to successfully test for it, which is why a special tester the editor listed below is recommended.

However, there is a very rare type of diamond (Type II diamonds) which has an unusual chemical composition (it does not contain nitrogen, it contains boron) and this makes the diamond electrically conductive, i.e. it will register 'Moissanite' on a diamond tester. If you are not a diamond dealer handling thousands of diamonds, it's unlikely that you will ever see one of these.

This is important because a metal prong will register as diamond on most diamond testers that lack a metal warning. If you will be using the diamond tester in multiple locations, you will want one that will test diamonds accurately across a range of different room temperatures. After all, you are doing a thermal conductivity test. If you are going to be testing diamonds in large numbers, you will want your diamond tester to warm up fast and to have little or no lag time between tests.

Consider investing in a diamond tester that comes with a protective probe tip or at the very least, a carrying case to securely house your tester when it’s either not in use or is in transit. Powered by batteries - battery powered is an excellent option for portability but also consider whether you’d prefer the option to have a secondary power adapter source or even a USB charging option.

Sandpaper can be used to distinguish some fake diamonds from real ones, but this is not a completely reliable test either. X Research source If it's not a real diamond it still might pass the scratch test, because many gemstones are very hard — or, if it fails the scratch test, you just needlessly ruined a jewel that looked just like a diamond.
