    Thanks, Richard for this. Of course, a legal standard of
    fineness is not a term we mention very much in New Zealand, where
    legal standards are not so defined. I will use any particular
    silver or gold alloy for its inherent structural and other
    physical proporties before I'll consider any legal definition.
    And that's fine here in this country. 800 silver is great for
    many uses - especially in eyewear frames where strength is
    important. 900 is another I prefer sometimes over 925. (With
    copper as the remainder of the alloy.)

    I am very interested in the link on your page to info about the
    silver-Ge alloy. <http://www.twi.co.uk/connect/apr97/apr97i.html>
    I'm interested in this geranium silver. Sorry germanium. I
    wonder, is it something that can be done in the small studio
    workshop? And I'm also interested to learn that 1.1% Ge changes
    the conductivity of sterling silver from 96% down to 53%. How
    does this compare with gold alloys? Does this mean Sil-Ge ring
    shanks will be able to be soldered with stones in place more
    easily? Hmmm...
