What materials can I use for a decorative infant urn?

I've had my daughter's cremains in a temporary urn for almost two years. I couldn't bring myself to move or even look at her cremains. She's been stashed far away, and for a long time, I just wanted to do the impossible and forget. I feel that I can finally face it and make peace with it by paying tribute to my baby with a beautiful urn. I want something that isn't too fragile and something that is a bit artsy to display in the living room.
