Shirel Diamonds Herzel Cohen fake DGL certifications ramat, Internet

I found Herzel Cohen on Alibaba.com as a distributor of diamonds and bought a stone from him.  It was supposed to be certified.  When i got the certification it was done by DGL.  There is a DGL lab, whose website is http://dgl-labc.com.  this one was a fake. the website was http://dglaboratories.com. (notice the spelling)  the website is a shell with only a few navigable pages.  And their email address was at a hotmail account.  I tried to verify the certificate, but the link to do so only takes you to the pricing page.  I had emailED Herzel about this and he got all offended saying that the lab was a real and respected lab in Israel.  So I emailed the lab on their hotmail account...and guess who replied....HERZEL COHEN!!.
the stone i bought from them was not the clarity listed in the certificate and no one should "certify" their own stones.  Also, I was charged $30 for the certification and then when I used Paypal, Herzel told me that I need to pay more to cover his Paypal fees, which is his cost of doing business, not mine
They also go under the company Shirel Diamonds, http://www.shireldiamonds.com.
DO NOT BUY FROM THEM
