Don’t know since when is, as long as it is buying a diamond ring who asked us to provide the GIA certificate, although this kind of thing is very troublesome but we’re happy to do so, as do those illegal pedlar is a lot less then the opportunity, so our diamond market can thoroughly purify. These things to us these formal jewelry shop is a hundred benefits and harm no one thing, so now we are even in the face of those who did not ask for the GIA certificate will also give some pertinent suggestions, let their legitimate rights and interests can be well protected, I believe this is what we should do.
