IS this accurate for other gemstones?

Hi, No, not really; for gemstones my suggestion's a Presidium Duo-Tester. It's pricey.

This worked for me on sapphire crystal and diamonds, but I am not sure it would work for other gems.

This scale does read grams to two decimal places. I weighed my silver jewelry and got results like: 3.37 and 18.02 grams. I hope that this helps.

I ordered this for my mother, she hasn't had any problems with the reading been inaccurate.She takes this to her doctor to have them check it against their reading and it has been fine.I hope this information helps. Joyce

No- but I would stick to gold and silver. I would imagine they would clean or buff up your gems but work visibly on gold and silver. I use it on my wife's diamond gold ring and I have to say- it sparkles like new with No effort. I also use it to clean my stainles steal watch and crystal.

Some times they use the same picture for all stones so I would believe the description.

I can not answer that but what I did was take it to the nurse where I work and compared their readings to mine using their equipment vs mine. The results were very close. The nurse was happy with the comparison. She said it is not an exact science.

Yes, but you need to be a pretty good judge of the size of the stone. There are different settings, depending on the weight of the stone.

I bought a 200 gram capacity digital gram scale on amazon for less than $15 and it's pretty accurate. Mine weighs to .00 grams which would work for your purposes. I think it's great for culinary and cosmetic measuring purposes (the small stuff of course). I'm not too sure about that cheap of a scale for something as pricey as precious metals and gemstones although it does weigh carats too. You can also get the 100g and 200g weight to calibrate the scale for better accuracy overall. People who said to use a kitchen scale with a 1 gram increment are pretty far off the mark, it seems like they didn't think that through. I do use a kitchen scale that has 1 gram increment but that would not be accurate for these smaller amounts. You may find that one of the measuring spoons is close, but you would have to test that out with a gram scale first.

The S80 appears to be accurate compared to charts and the 3 that I have. Not sure what the "mobile" version is, they are the size of a cell phone and mobile so can't help you with that one.

5 3\4" would be accurate up to 1/16" is the length of each stone by a little over 1 1/2" but not quite 9/16"

Gemstones are not labeled- shouldn't matter. I don't remember instructions. Know you can jump north to south, east to west only-- no diagonal at all-- it is a lot of fun. Object to get the least amount of stones left. Remember to take out the middle stone-- there will be two extra.

I've noticed the same thing. Not sure why, but the readings seem pretty consistent over time so I think it's accurate.

You can use it on gold, yellow and white ,,platinum and most stones. Not pearls.

noooooo, the pressure is too great. sonic cleaner is best for most gemstones. or u can use ammonia water on them with a soft bristle brush. do not use ammonia on coral, jade those types of gemstones it will damage them.

I can't answer your question. I paid for my stone but NEVER RECEIVED IT!!!!!

A gemstone? I don't really think so unless you are cutting a microslide of a mineral ore, for that kind of augmented view you should use a Stereoscopic Microscope :)

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.
