There seems to be a few small to minor issues with the description and summary of the story:

She does noy know the powers it contains,

; would be:
She does not know the powers it contains,

This gem seems to glow a faint red and pink color.. She has never seen such a gem before and it intrigues her.

; would be:
This gem seems to glow a faint red and pink color. She has never seen such a gem before and it intrigues her.

And finally, it would be better to have 2 spaces after the sentence? By adding the second pace, you denote the difference in punctuation and makes the text easier on the eye and more readable.
At least, it is how I feel.
