I agree as well. It's a lovely display item. I keep a number of shells, agates and other materials that I've bought as cutting rough in the house. Visitors enjoy looking at them. Do you happen to know if it is cultured? It has the appearance of one. If so, then I'm sure that if you wanted one for a piece of jewelry you could obtain another one for that purpose.
