Significantly more than 100% last I checked if you don’t buy wholesale. I went to Bloomingdales 7 years ago and they had “50% off” diamonds and the markup after that discount was still roughly 500% considering the very poor quality of the gemstones. People really get ripped off unless they do proper research. Even Tiffany’s was 2-3x markup, although at least I will say they only had high quality diamonds so that’s a point in their favor.
