A thermal diamond tester is a tool used by anyone interested in verifying that a gem is indeed a diamond. The tool uses electronics connected to a probe with a fine tip that reads the stone's level of thermal conductivity to positively or negatively test for the mineral diamond.

Can a rough diamond be tested by a diamond tester?

Yes, a diamond tester can detect whether a rough diamond is a diamond or not by analyzing its thermal conductivity. However, the tester may not be able to provide information on the specific quality or value of the rough diamond.


Is the faster the diamond tester beeps the better the quality of diamond?

Not necessarily. The speed of the diamond tester's beeping indicates the thermal conductivity of the stone, not its quality. A higher quality diamond may or may not beep faster, as factors like size and shape can also affect the speed of the beep.


How do I test quartz from diamond?

Have you ever heard of the Moh's scale? I believe quartz ranks 7 and diamond 10. If you can obtain topaz which is more common then Corundum and it leaves a streak on the mineral then the mineral is Quartz, but if the topaz or coundum is scratched then it is indeed a valuable diamond.


Would a light meter tell if a stone is an antique European cut diamond?

I think you are referring to the 'thermal diamond tester or thermal probe' (instead of light meter) but it will work on any cut. It tests the thermal conductivity of the material, so the cut does not matter or affect it. Thermal probe is not a confirmatory testing device to separate diamond from synthetic mossanite. Synthetic moissanite which has a thermal conductivity very similar to diamond and as a result gives the same reaction to the thermal testers, as diamond. Even highly included diamonds may give false readings.


Will a diamond tester test only diamonds?

You can apply a diamond tester to anything else, but the information you read on the instrument will be meaningless, unless you are testing a diamond.


How do you find out if a diamond is real besides testing it with a diamond tester.?

A 'quick and dirty' test is to pass the diamond over glass. If it cuts the glass, it's probably a diamond. Some 'fake' diamonds cloud up under cold water; a real diamond remains clear. Finally, a certified gemologist will always be able to tell whether a diamond is a real diamond, or a 'fake' diamond -- using a diamond tester.


How do you know if diamond brooch is real?

By using a Diamond tester on the Diamonds and checking the hallmarks, if in doubt, check it out and take to a jewellers


What is the thermal conductivity of a diamond?

The thermal conductivity of a diamond is very high, making it one of the best heat conductors among natural materials.


Does diamond demonstrate electrical conductivity?

No. Diamond is a thermal conductor, but an electrical insulator.


How do you test raw diamond at home?

Testing a raw diamond at home can be challenging without the proper equipment. One common method is using a diamond tester, which measures a diamond's thermal conductivity to determine if it's real. Alternatively, you can check for imperfections or inclusions under a jeweler's loupe, though this method is less reliable. Consulting a professional jeweler is the most recommended way to accurately test a raw diamond.


How do you test if a diamond is real at home?

You can test a diamond at home using a few methods. The first is the fog test - breathe on the diamond, and if it clears quickly, it's likely real. You can also try the transparency test by placing the diamond over a newspaper, if you can't see the text through the diamond, it's likely real. Lastly, you can use a diamond tester that measures thermal conductivity to determine if the diamond is real.


How do you see if silver has a real diamond?

You can verify if a diamond is real by performing a few simple tests. One common method is the fog test, where you breathe on the diamond to see if it fogs up (real diamonds disperse heat quickly so they don't fog up). You can also use a loupe to look for imperfections or a jeweler's tool called a diamond tester to measure the thermal conductivity of the stone.
