The prices for precious gems is dependent on supply and demand - not on any particular physical property. If people prize a certain gem above another then they will pay more for it.Consider diamonds and Rubys. Diamonds are harder than rubys, in fact they are the hardest mineral know - yet Rubys are considered more valuable.
No way.
