You can win me and lose me but never buy me
You can not eat me and never want to part with me
I can make you cry or bring you joy

You keep me but i am not forever just yours
You might find me in a case or on a shelf next to a vase
I am hard and i am tall if you bump me i am sure to fall
I am made of different materials and am at many events
If your lucky and fight hard I might be yours
What am I ?
