I'm going to speak in terms of dollars because I'm American and I'm too lazy and lacking in math skills to figure out the conversion.
You are correct that the mark up is higher on smaller stones. But it is nowhere near 1000%. On larger stones (over a carat) it's not even 100%. I deal in high quality diamonds now but I've sold crap in the past and I'll concede that you get jacked a little harder on those, but not to the tune of 1000% what the jeweler paid for them.
I will also give you the benefit of the doubt that overseas it may be as you describe, but it absolutely is not the case in the U.S. Does that mean there are NO US jewelers who do this? I can't say for sure. I can say for sure it's not the norm.
