Pearl

Pearl of the Crystal gems tends to be a real stick in the mud - but there's something very appealing about her. She's flawed, but she keeps trying, and even though she knows that she's not as strong as a lot of other gems, she works to be the strongest that she can be.

She also has a very twisted view on the short lives of humans, but hey, if you lived forever humans would appear to live short, ironic lives.
