It's easy to make.
1. Find an old metal kitchen colander (or metal lamp shade). You want something with holes in it (or you can use a metal drill bit and drill them).
2. Using 16 gauge wire, wrap around marbles and hang crystals from the ends. You could thread transparent beads onto the wire. Pick colours you love.
3. Attach flat-bottom marbles or other decorations on the colander using clear-drying outdoor silicone sealant.
4. Add wire to the top and hang the chandelier outdoors.
