However the original manual says that the island moves because of the Chaos Emeralds, and given the Chaos Emeralds have not been to South Island for who knows how long, who's to say South Island is still a mobile landmass?

Japanese manuals also say that South Island is a "treasure trove of gems/jewels" so could be possible the island has it's own beryl deposit which chaos energy running through it independant from the Chaos Emeralds.

But given the only gemstones found in the games are the ones in the early Secial Stages (if they coult as part of South Island) we've yet to know if there is any other minerals on South Island.
