So the site said I have won the bid then when I go

to pay it said I lost?? Have been on this site for years so what is going on?

I do not think it is random people overbidding.I have been bidding on this site for 5 years and I really believe it is the site placing fake bidders to bring the cost up.Also why is it that the est value of a gem is at 600.00 dollars then magically a few months later est value at 150.00?? HMM... not...
