Pearl loose beads wholesale spent because Mrs honey-water testing is destructive testing ~ ~
Measuring only their own collections to the seller of goods can not test this ~

And the experimental results ~

There is no practical use ~

There a test to traces of corrosion
Buy or not to buy very troubled ~
