Long time listener, first time caller. I'll hang up and listen to your answer. Thanks!

Sterling is a specific purity. Karat is a scale.
--Severian the Lame
"the unit of measurement for the proportion of gold in an alloy; 18-karat gold is 75% gold; 24-karat gold is pure gold"
I guess it only pertains to gold. Period.

Maybe cuz there's not enough silver alloy things that transact publically to warrent a fractional silver purity scale???
Too many positive BST transactions with too many members to list.

Maybe. But we're all familiar with at least 4 levels of purity:
40% (65-70 US clad coinage)
90% (pre-65 US coinage)
92.5% (sterling)
.999 pure
Additionally, Canadian (non-penny) coins from 1920-1966 are 80% pure.
English coins from 1920-1946 are 50% silver.

What about diamonds?

Spelled differently. For diamonds the word is "carat".
"Carat Weight
It is a common misconception that carats refer to the size of a diamond. In reality, a carat is the standard unit of weight by which diamonds are measured. One carat equals 200 milligrams or 0.2 grams.
Carats are also expressed as points, with one carat equaling 100 points. So a one carat diamond is also referred to as a 100 point diamond."

40%, 50%, 80%, 90%........that's content, not purity.

I think that's semantics: Purity denotes "a quantitative assessment of homogeneity or uniformity". If you're addressing the specific ratio or percentage of silver in an object and you're not interested in what other materials might be included, you're talking purity. If you're looking for the copper and the silver and the zinc, etc., you're talking content.
