The Sol Emeralds (ソルエメラルド Soru Emerarudo?) are objects that appear in the Sonic the Hedgehogseries. They are a set of seven emeralds of great power that originate from the Sol Dimension. Just like their inter-dimensional counterpart, the Chaos Emeralds, they are usually sought out by heroes and villains alike due to the power they possess. They appear in Sonic Rush, as well as in its sequel Sonic Rush Adventure, where they are guarded by Blaze the Cat. They are emerald cut gems, as opposed to the brilliant cut Chaos Emeralds.
The Sol Emeralds share a similar role with the Chaos Emeralds in the modern games, as serving as necessary plot devices in order for the game's story to progress.
