Rim of the alliance emblems

the rims of the alliance symbols, emblems, shields,(whatevs u want to call it) are wooden, bronze, gold etc… what do they mean/represent?

Gold means you came first in your last alliance war, silver means you came in second, and bronze means you came in third. A wooden edge denotes coming in 4th, 5th, or 6th.

If they have a wooden edge, then you know they have no war boosts.
