This crown can be used as an accessory for the medieval dress or other occasions. I added a diffuse-texture, you can use this in Blender as well. But I propose to create an own material in Blender. Therefore I added a small example node setup as an image for blender ("misusing" the optional bump texture). Of course you can also use a PBR shader or take gold instead of brass. The crown will intersect with many polygon hair-dos. If you are working with strand it is also not so simple, I tried my best to create an example picture ...
