Now 18 karat gold is 750 parts of gold for 1000 parts of metal, and
is the international minimum standard of quality gold in the
Is that a pseudo standard, although I sort of agree, I can't say
I've read it anywhere. No it is trade standard amongst fine jewellers
such as Hardy Brothers, Tiffany and Stuart Devlin.
If you knew what a 6mm round A grade sapphire was worth you would
know that my bullion dealers are in fact very reasonable on price and
I use them because of the exceptional quality of their metal.
Not all bullion dealers produce equal quality of product although the
metal fineness may be the same the working quality and finish is not.
For my 18kt ring bands I buy soft fit precision made, and pay a
premium for premium quality. The extra cost is more than made up on
the time I save in making. Customers also prefer hallmarked rings
from a leading bullion dealer. Something about provenance.
Just because there is a standard for 9 karat/carat gold in Australia
does not make it anything else but crap. Why? 9kt looks nothing like
gold and tarnishes easily.
Quality jewellers simply do not use less than 18kt. Educated
customers do not buy less than 18kt gold.
