Treasured Gem

Rose was allowed to find some treasure, according to Solari himself. She was a little scared to go in the dark, but decided to go in a cave to investigate. Three minute later, Rose noticed something pink and sparkly; it was a beautiful glittering gem! This smart little kid picked it up and saw it. It reminded her of her mother's old jewel.
