It's so sad to see these going for 60s. Back when I was i my 40's before Burning Crusade came out, I made a good living just selling these pearls. They sold for over 50g on AH overnight almost as many as I could find. They were a lot more rare but I knew where to get them in good supply. I think the reason they are so overlooked now is that when you run some of the Zangarmarsh instances, they drop pretty frequently from mobs. When a whole lot of people sell an item it depreciates in value to become almost worthless. I'm glad you found a way to get some money from them. For me it was just never worth the trouble trying to sell them.
