Wishing for snatch?

[Sir_Dr_D]

There is some themetic problems with gem producing items. If in the world of dominions anyone could create these items, woudn't the world get so overpopulated with these gems that everything except astral and fire becomes irrelevant? As it is, it seems that the world naturally produces gems at a steady rate, which keeps a balance. Magical energy seems to come from somewhere. Where does it continuously come from for these items. Shouldn't they have to suck life out of the surrounding coutry side, or something equivant, in order to get the needed energy to create the pearls?
