Platinum is an ordinary IceWing dragonet. She has platinum scales and bright blue eyes. She wears a silver medallion. She also has garlands of crystals around her horns and on her neck.
Platinum's personality is a whole mix. She is grumpy from time to time, and is a little sassy. Okay, really sassy. She has an immense crush on Copper, mentioning that is was "true love at first sight". Of course, Garnet has a crush on him too, so they both argue over him a lot.
