Testers for diamonds, and Moissanite

I would like to answer your question, but Amazon did not forward it to me. I can only say that I have had good success with my purchase of the Dusiec Diamond Tester. It performs simple tests on diamonds and has proven accurate each time.

I have not tested on Moissanite, but know it works when distinguishing between diamonds and good rhinestones

Moissanite was specifically created to be as close to a diamond as possible, therefore, any inexpensive diamond tester (such as this one) will give the same reading for diamond as Moissanite.

No it doesn't not.. the very first line in the instructions says "Moissanite Not Distinguishable".

If the diamond looks to be about 1/10th of a Carat or larger, put it on dial setting 4 (the lights will light up to #4. If it is smaller, set the dial at 6. After setting the dial, take off the cap and press the thin metal nose directly against the top of the diamond. Be careful not to touch the metal prongs, for this will give you a false reading. If it is a diamond, all the lights will light up (even the red ones) and it will beep. If that doesn't happen, it's not a diamond. I recommend that you test something that you know is a diamond to get the hang of it.

I haven't used mine yet but as I understand most all metals. It has different settings for what particular metal you are wanting to detect.

I bought them for pmc and polymer clay pendants and they're good for jewelery sized shapes.Michael's crafts should have a few too to compare size in person.

With this meter you would have to grind them up and make a solution and then place a few drops on the testing strip. But just call the company and they will help you.

The diamonds are 1/2 inch across and 1 inch long and the big diamonds are 1 1/2 inches across and 2 1/4 long

You really can't. All that it tests is diamonds and diamond stimulants. The only way to test a gem with this is to loupe it and see the cutting of the stone. All this does is tell you if it is a diamond or not.

I don't know for sure but they are diamond tipped and should last a log time, plus the price was very reasonable.

have never tried it but glass is harder than granite so I see no reason why it would not. diamonds are very hard. just remember--GO SLOW and use plenty of water.

I think that the stone IS a steel plate. I think they have bonded diamond dust to the top of a flat bar of steel. Whatever it is, it works great.

It is hard to test a stone in the setting. All the stone i have tested is without setting.

Yes, this would be an excellent use for this tool. Be sure to check a known power source such as a receptacle to ensure the tester is working properly.

I saw someone demonstrate this product on sterling silver and worked very good. BUT my purpose in buying this was to check for old jewelry - namely - "Bakelite" It will turn a q-tip green if the item is bakelite.

YES! You can test any sized stone as long as the stone is touching the metal tray and your finger is as well. The back of the tester has a metal plate that you must be touching with your other hand to complete the grounding circut.

This device only confirms if a stone is a diamond. You can check other stones but it will only confirm if the stone is a diamond. Diamonds do come in different colors

I'm not sure of your question.. Li means nothing to me unless "light index" or something like that. RI is the standard term for "refractive index" which is what this device measures. Older testers used a very nasty and short lived chemical to bond a gem to the tester, and they had an analog readout. The accuracy of this is at least as good as the older machines.
