Jewel Crown

How can "spark" as a "jewel in the crown 'for my showcase?
just to let you know that I am using my mom's account to ask this. ok I'm in a summer showcase of ballet and my character is the Jewel of the Crown. the only advice I received from my master was to be sparkely and smiles! my show is this saterday and I'm still not sure about my character. I thought of a jewel that things like this: refined grace pretty glowing a little proud and other things I can not think now the thing is that it is difficult to put it all into quality along with the dance! please give ideas or advice on how to act and dance like a jewel. PLZ say something when you get to this page. Thanks for your help!
do all those things and what I like to do is like a little flirting with the audience with my face and eyes. or dancing in front of your crush and how you want to look beautiful and comfortable on the stage as if being there and even his thoughts on stage and dance a little still want to flirt with that crush .. Do not get nervous thinking that .. just think it and as you become the dance:) goodluck.
