You will need: a black straw (black is best) cut into 3 equal pieces about 2" long, a cap from an old bottle of lotion or something like that (black is best), a glue gun and glue sticks, and a gem (I got a whole bag of them at the Dollar Tree).
First you glue on one of the straw pieces.
Then glue the other two on forming a triangle.
Then pinch the ends together with a little glue.
Then place the gem on with more glue. That's it!
Here is the finished trophy!
