If this is an opening paragraph, squeeze a little more information and some characterization out of the scene segment while keeping it moving within the overall scene. Also, calling the brooch elaborate doesn't alert the reader to the value of the object in the terms you intend.
The following is not a direct suggestion, but an example of how one could incorporate the original writing into what is presumed to be an action scene (battle?)
[POV character's name] wiped the smudge of blood from the brooch and admired the ... [give some brief physical detail that will identify it as coming from a person of importance]. The Norseman wouldn't need it now. [POV character] turned the prize to catch the light. He'd never seen [another chance to give another brief detail, but this also underlines that the POV character is of a lesser social standing].
[Have something else happen to get the character's attention and to keep the scene moving]. [POV character] gathered the fur-trimmed mantle tight around his neck and fastened it with the brooch. He felt a sense of awakening power, but was it from the brooch or from the kill? [Have something happen to him that immediately challenges the sensation he just experienced]
Now we know the POV character is a warrior who just defeated a Norseman of some social importance, and the reader has been alerted to how special and important the brooch is to the character. Presumably the brooch will play some important role later in the story, and the brief physical descriptions can be used in those later appearances. Also, the scene isn't a static description, but incorporated into a moving scene (if that is what was intended). Why keep the scene moving? If it's a battle scene, he won't have much time to admire a trinket, no matter how important or beautiful, so the challenge is to get that importance in the mind of the reader while keeping up the action of the scene. If the scene is the aftermath of a battle, there will be more time to dwell, but still no need to hit the description of the brooch much harder. The aftermath of a battle is a time to get into the mind and reactions of the warrior to set some serious characterization.
