Silver, Fine silver, Sterling silver


#1

Hi to all,

Well until today I have been using what we call 925 Silver, I assume
that is a mix of plain silver and maybe copper or something else, I
have been reading many posts and they refer to sterling, fine and
silver and I think all of this names refer to the same metal but the
mix changes maybe with the addition of other metals. Am I right, or
not,

Thor, you are right, but you seem unclear, and this is fundamental
stuff. Fine silver is 99.9% pure - it is called fine because it is
not precisely “pure” - getting the last.1% out costs a lot, and you
can go to a chemical supply for “pure” (CP in chem terms) at $100/oz
or so. Sterling silver is an alloy - a mixture of metals. Traditional
sterling is 92.5% silver (or 925/1000) and 7.5% copper and nothing
else. It’s like the “how to roast a turkey articles” around
Thanksgiving. I guess there are some things that need to be
reiterated from time to time…

Hi Thor,

fine and silver and I think all of this names refer to the same

In the US Sterling Silver must be at least 925 parts per 1000 pure
silver. The other 75 parts can be any other metal, but it’s usually
copper. Fine silver is required to be 999 parts per 1000 fine
silver. The other 1 part can be anything else. Both of these
requirements are written into our national laws.

Argentium can legally be called sterling because it contains the
required 925 parts of fine silver. There’s nothing in our laws that
specifies any adjectives that are applied to a product that meets
the requirements of the of the defined ‘precious’ metal. The
Argentium name is a marketing tool to differentiate it’s unique
characteristics from ‘regular’ sterling.

just uses the word silver I assume sterling

Thanks Dave for the that is what I thought but so many
people where asking that is good to refresh our knowledge. By the
way the Koil Kutter is working nice, still using the same blade and
also I have told many of our jewelry students where and whom to buy
it from.

Hi Thor,

Yes, you are right. If a person speaks of “silver” I would assume it
is a generic term and they are not defining the alloy or lack of
alloy. However, “sterling silver” refers to what you call 925 silver
(or .925 silver, usually meaning 92.5% pure silver and 7.5% copper)
is sterling silver. Fine silver is .999 silver (99.9% pure silver and
0.1 other impurities, or what is considered pure silver). There are
other alloys, but I really don’t know much about them.

I hope this helps!
