I couldn't get the picture big enough, but the first few runes are Othala, Raido, Kenaz, Nauthiz, Isa or it could be Ehwaz (I'm guessing a bit here, since the detail was kind of blurry). But that would spell (more or less) Orkney. The rest I couldn't see clearly enough. Although honestly, it looked there was a mix of at least a couple of different futharks in there...some of those runes look more like gothenburg than elder futhark or even anglo-saxon or any of the others I have a little familiarity with.
The runic enamel earrings ARE lovely. I'm also rather partial to the Ogham piece. Although I can't read that one as easily. :)
