how do I test gem's other than diamonds?

Depends on the gem in question. This is only intended for diamond testing. Other gems have other methods of testing.

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.

Try turning it off than recalibrating it. It should read 9999.99 and count down to 1111.11 and if that don't work than you might have a defective 1.. It's life time warranty so just send it back to gem pro.

I don't know. The easiest way to test it is to take strands from the nape and test them on a hot roller or curling iron.

This may work If the diamonds are impregnated on the edges of the disk. They have what Is called a cutoff disk you can use them with the same Dremel tool. Those are meant for the problem you have.

If you look up nail gems you should find something like this that has an assortment of shapes including square rhinestones.

Most of the work I have done is with small parts.Makerbot. works well at this.most parts have micro lines thst do not effect machines,but Jewelry would have to be sanded and finidhed to your likes.

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.

Have you tried calibrating? I bought two and they were just a smidge off, so calibrated and they are perfect. You might try changing surfaces it sits on. I was at a gem show last week and many vendors used this specific scale.

I'm really sorry, Orlaina, I don't own one of those to test them with. Checked with friends as well. No luck. :-(

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 would not use this on all gems. The cleaner is designed for silver flatware and housewares, not jewelry. It could severely damage opals, turquoise and similar soft stones, coated crystals, and pearls. If you need to clean silver with gemstones, use a cleaner designed for jewelry.

I just ordered one myself. Hope it comes with instructions, utube has some diamond testing videos, from what Ive seen , turn it on , make sure your diamond is clean, gently push the tip on the top of the diamond, if the reading turns green it real, if not it wont do anything . The best thing to do is try it with a real diamond and a fake stone , see what happens. Let me know if you get it figured out, might have to write back later and ask you for help, good luck.

It does not specify types of jewelry. It just says Necklaces, rings, earrings and bracelets. I personally have used it on some birth stone pieces.

I didn't have my tester hold the diamond at all, I just touched different stones and it worked.

For some types of jewelry, instead of an opaque white backdrop, it's better to shoot on a lightbox. (You can create a "lightbox" with translucent plexi and a light underneath) You can get the under-light bright enough to blow-out ground shadows and for true ultra-white background, while still controlling the lights on your product from the top. Gemstones often look good with the light coming up through them.For macro work, you'd not need an entire roll of seamless paper. Just use some high-quality printer paper (like Hammermill 24# laser print or Hammermill 32# color copy paper) that's very smooth and very white and fairly matte. Unless you are doing some extreme side-lighting, you won't get any texture. For some types of jewelry, instead of an opaque white backdrop, it's better to shoot on a lightbox.

The key is accuracy. Depending on the area of the table you can. The measurement area for the laser is about 2-3mm across. Your best bet for smaller mounted jewelry is to get it professionally appraised. The last thing you'd want is to get a false negative because the mounting threw off the reading. Again, it depends on the size of the table. I've used it on mounted rings, but they are larger carats
