Where do you think the Chaos Emeralds came from? In the only two instances they were explained (STC and STH series) they were gems fueled by some type of radiation... the only difference is that the STH ones were natural while the STC ones were augmented Emeralds from the Echidna's sacred emerald mines. I have a theory.

Perhaps they were formed when Mobius came into being, and were very plentiful all over the world. However, as Mobius aged and grew, the Emeralds dwindled in number, until only seven were left - the ones that we've come to know today. I guess they had the most power inside them that made them outlast the rest, same thing with the Master Emerald.
