Royal Gem

This is a gemstone that can only be owned by those related to the royal family. It is a masterful example of a technique known only to the royal family's alchemists. In the past, some fools desperate for money tried to pawn some off, but they were turned away because its value was beyond anything that could be paid for with money. However, after a method to mass-produce these gemstones was found, they became readily available as souvenirs for tourists.
