37% is enough to control the market. > Not entirely true. Diamond prices fluctuate and have appreciated in value over time Which wife wants to wear a used diamond? You probably are in first-hand sale and you don't resale. Diamond are like new cars; the moment you take it off the lot, it loses 40% of the value. You coudl truly bring it next day to same seller and he will offer you 30-45% less simply because "I have to be honest and tell new buyer its been worn before". > You can say the same thing about art. Diamonds are collectors items. No you cannot say the same, as Diamonds are not art. While each diamond is unique, their uniqueness does not add enough to value in order to justify holding it as a collector items. Their uniqueness is equal to each $1 dollar bill being unique because each have unique serial number. Unless you keep very unique Diamond, majority of them will depreciate in value. Most art is unique from each other; I mean we just had few hundred millions bid on some popular paintings down at Rockefeller auctions; can you point me to any article when someone purchased diamond for X and sold it for Y, while Y > X ?
