Jeanne, the stone is a norwegian unakite.
It contains green epidot and red to pink feldspat, and very often
some lines of white granite. You find it in belts and in granite
along roads, and often in pieces along rivers, rounded and quite
cute.
I have cut and polished a few, it gets a nice polish.
If you collect some norwegian stonebefore ypu leave us, do not
forget the Larvikitt (blue labrador, which they sell as Blue Pearl
for benches and bathrooms) either, it is also filled up as roadsides
around Larvik/Helgeroa/ where they have a big billion industry with
this. The stone gets a nice polish, look at it how its broken, the
glow comes best our one way. There is so much of this that you can be
really selective to find pieces with big blue glowing spots and cut
slices to bring with you.
I will tell you off list exactly where you can find very nice
excamples of the unakite, a little more than an hour with car from
where you live.
I’m sorry I do not have pictures of them both ready polished, only
some cut into pieces.
