Inflated and false certificates

I recently purchased a diamond with a certificate issued by GISA stated:<br> Round cut diamond 1ct<br> Colour J<br> Clarity Vs2<br> Natural Diamond<br> Comments None<br> I took it for certification with EGL in Johannesburg where it was certified by 4 different gemologists and was rated as follows:<br> Colour Brown (ecg) Q<br> Clartity I1<br> Invoice No. 53555.<br> I could not believe what They said and took it to GIA in the same building for an opinion who rated it the same.<br> Beware of Gisa certificates as they inflate prices and grades to suit their clients. They are not accredited and registered with the South African diamond and precious metal regulator and their certificates are not worth the paper they are printed on. They are ***** and make up their own grading system and they certify gems at least 5 times higher than their actual value and **** potential buyers.<br> <br> Stay away from gems certified by them, or pay the price of paying a lot of money for worthless items
