Krystyna Nowicka / M10 (Martien Verheyden)

Mixing gold and silver can sometimes lead to, well, mixed results (to my eye, at least). These pieces, however, blend the two metals elegantly and organically. Rings above by Scotland's Krystyna Nowicka. (I've been keeping an eye on her site for over two years and it seems to have some database issues that aren't going away, so please note that you might not be able to view much of the collection online.)
