Very happy with testing stone
One of my best purchases. Grabs a good amount of metal for testing without a lot of impact to the jewelry I am testing. Easier to read results on this stone compared to the one provided in my acid testing kit. Very good product!!!

Works as intended
Works as intended. The first stone I received was completely shattered from shipping because it was sent in just a poly envelope with no padding. The second stone survived with same shipping style. Other than that the stone works great and as intended and is larger than the 2x2 stone that most kits come.

Nice smooth testing stone.
This stone is smooth and does not ruin the surface of the metal being tested. It is so much better than the other stones I have used. It functions exceptionally well.

The real thing
It is a great size when you are testing many items, also it is the real thing. It works well when you sample the gold not like those plastic coated ones.
