Can anyone identify this brooch

[Huskarl]

I just dug this up in Reykjavik and I'm wondering if anyone recognizes the style, potential,age and material (probably bronze)

Hi Huskarl -- I responded to your other query, and didn't even know there was a jewelry forum here (now I'm in heaven, lol). If you can show the back, this will help greatly with dating. Nice find.

Any idea what this is? I think its copper.
