I'm not sure where granite is on the hardness scale, but, the blade had trouble with 3/8" granite tile.

I use the cerium oxide to mirror polish gemstones. I have used it to polish the crystal on my watch and it does any outstanding job. Gordon Glass Cerium Oxide is the best that I have ever used.

Possibly with a very steady hand or if the gem is on a flat surface. I discarded the one I bought and bought a very high powered Jeweler's loupe. Good luck.

I Have not ever worked with stones, but it works very well on towels. Don't see a reason why it wouldn't work.

I use it to polish sapphire's and ruby's for me at takes a while as I start it with the stones very rough and have to change the sand several times to get them to the stage of polishing them. electricity is not much but it is noisy so you may want to put it in a room by it self. try it for about an hour than check them as make sure you get the right sand polish for them too coarse can scratch them. I bought mine about 6 months ago and it is still working fine today.

One has to cut a window on the stone. If you have a flat smooth surface, it should work but I always cut a small window to make certain. The surface always has to be extremely clean

I would think so since on the Knoop hardness scale glass&ceramic; is 400-550, porcelain floor tile is 500-650, and granite is 550-650, tungsten carbide is 2000 and diamond 7000. diamondsure.com/materials.shtmlHope this helps.Charlie

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

As long as the crystal or gemstone has transparency so the laser it uses can penetrate, it will work just fine on a raw uncut gemstone.

I would not recommend it, stone is somewhat degradable. Maybe if you use the coarser side of the stone.

Hubby says that all the diamond tipped ones can be used on stone or glass. ( the granular embedded ones). Hope that can help you!! :.))

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

I'm sorry I don't have the expertise to answer that question, but any competent jeweler should be able to tell you. I know there are certain stones that are not recommended to be used in an ultrasonic cleaner, and especially costume jewelry where the stones are held in place with an adhesive do not fair well ( personal experience) but well mounted stones should not be a problem. When in doubt, a professional jeweler should be consulted.

It says not to use on other metals, pearls or porous stones. I am not sure about sapphires.

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 really don't know the answer to that question. The Hone itself is great. If the stones slide over the bar that goes in the hone it should work. What are you trying to do?
