Why does De Beers' sell bags of uncut (and unappraised) diamonds for a single take-it-or-leave it price?

Yoram Barzel, writing in 1977, argued...  “Had the contents of a particular bag been available for appraisal by all buyers,” Barzel explained: “[E]ach would have spent resources to determine the properties of the diamonds. …

  1. Hi viewers online, I'm Suzanne Gratton from the US. I'm here to share my testimony about how I helped to get my husband back. I was a cheat and my husband caught me several times. I tried fixing myself and each time I ended up cheating over and over again. I guess I didn't realize what he meant to me until he had left me alone. I began to find a way to get him back but nothing seemed to work out perfectly until I came across an article about DR PATRICK who helped a lot of people globally to get their relationships back. I made contact with him and he assured me that my husband will come back to me within 48 hours with his powerful magic and I paid 410 dollars for the materials needed for the work. Surprisingly, my husband came back home after 2 days saying that he still loves me and I swore never to cheat on him anymore. All thanks to DR PATRICK. You can have a chat with him on his WhatsApp number +1 662 493 2087 or you can contact him on Email and here is facebook page and his blob
