Rose-Quartz is the 10th sister, thus making her the youngest. She is sweet, nice, playful, cute, romantic, and tender, thus making her (or so Ruby says so.) The most weakest out of the sisters, and is the most playful. She would rather be pretending, running around, and playing then doing anything.

Rose-Quartz is full of friendship, affection, harmony, inner peace, and approachability. She will except any nice person to play with her.

While insightful and kind, she is also very sensitive, intuitive, and full of empathy. She does not like being yelled at or being blamed for bad things.
