It works as advertised & I like the relatively large size of this stone compared with other stones available in the same price range.

l didn't expect that I would be able to make it work for me but I was wrong. Just scratch your jewelry on it and place a drop of acid solution and you're done.

This stone is WAY better than those tiny white stones. This stone works VERY well. I almost threw away my 2x2 whites after I got this one.

Its not a stone, its glass. This is terrible, The acid just runs off your scratch with the particles and you can't tell between real and fake
