The Prussian Order of the Red Eagle (Roter Adlerorden) was awarded to both soldiers & civilians to recognize valor on the field of battle, excellence and  long and faithful service to the kingdom.  

This is the Grand Cross Breast Star of the order.  It is a gilt, eight-pointed breast star worn on the left chest.  It was typically awarded to male members of the royal family, to members of the Order of the Black Eagle, to "nobility" and to foreign royalty.

The swords indicate distinction in wartime.

This is a beautiful replica of the badge.  It weighs 2.8 oz. (78 grams) and measures 9 cm across.  It has a pin and catch mechanism very similar to the originals and the workmanship is superb.
