Black Diamond Silesia Miners

A concept of a logo for a Quidditch team. Black Diamond Silesia Miners is a Quidditch team from the region of Upper Silesia in Poland.

The logo consists of a diamond (coal) and a pickaxe which communicate coal mining - which Upper Silesia is famous for and which the team's name refers to - as well as two brooms which communicate Quidditch.

The yellow and blue color scheme is based on the Upper Silesian flag and coat of arms.
