Blue Topaz

Blue Topaz is one of the active Gems residing on the Radioactive Island. They are the second hardest Gem.

Appearance
Blue Topaz has the standard Radioactive Gem uniform with no variations. Their features are blue. Their hair is styled in a slicked back manner and short. They used to have longer hair but it was lost by Sky Guardians thanks to attempting to protect Green Diamond from their behaviour.

Personality
Blue Topaz appears to be a very serious Gem as they are constantly compared to Green Diamond. In reality they're attempting to keep the egotistical Green Diamond from doing anything reckless and mean. They care for others a lot.

Character Profiles

 * Levelheaded. Tries keeping Green in check.
