BIO: diamonds father ran a mining company when she was a filly so he wasn't exactly around very often but he left her a good life. She did get to see her father sometimes though, like when her dad took her to the mine once a month and let her visit around.
She still has a little ore in her house from when the miners would give it to her.One day when her dad had brought her with him there was a cave-in and she was trapped. Everyone panicked besides her because she didn't realize the true gravity of the situation and she had hope in her daddy but after a few hours she started panicking and took a pickaxe then started digging her way out. The other miners had been trying this but she hit just the right spot and not only did she get through but she found a small amount of diamonds along the way. When she got out her parents were crying but still noticed her flanks and the fact that they had a torch on them.
When she turned 18 she started up her cave tours near canterlot.
