Measure of the purity of precious metals (5)

Ross

I believe the answer is:

carat

(Other definitions for carat that I've seen before include "Not a large weight" , "Gemstone weight unit" , "Precious stone weight" , "Measure applied to gold or gems" , "Measure of weight of diamonds" .)

I've seen this clue in The Guardian.
