Its about the diamond market in general, not about the value of individual diamonds. I was hoping for the latter. Because I know someone with a blog about jewelry and once she received a $500 commission on a $6000 diamond sale (we assumed as part of a ring) through an ad on her website. So the seller must have made a good profit as well. Seems to me that diamonds are not good for investments other then a relationship.
