I find it interesting that the hallmarking debatein the UK is being presented as consumer protection for the average guy, as if it was such enlightened, progressive and benevolent government policy when medieval kings introduced it as a means to audit their treasuries. As Willis Hance has pointed out with some slick word-smithing you can still keep within the letter of the law and still flim-flam the uninformed consumer into thinking gold plate contains some serious precious metal value that might be a good investment.
Stephen, the reason that it’s presented as protection for the
average guy (or girl) is because that’s what it is. It might have
been introduced in the 14th century to protect the wealthy, but
there have been various acts passed by parliment in the intervening
600 years, and the system is now entirely for the benefit of the
consumer. Manufacturers don’t gain anything from it, and the
super-rich don’t need that sort of protection - they would easily
afford to have items XRF tested if there wasn’t a hallmark.
Carats are an increasingly outdated system - dividing alloys into 24
parts used to be a good way of working with metals, because 24 can
be divided by 1, 2, 3, 4, 6 and 12, but modern scales and the advent
of decimalisation have removed the need for that sort of
measurement. In the UK, we now use a system of fineness marks,
expressed as “parts per thousand” of precious metal content (the
remainder being metals of a lower value, like copper). There are
fineness marks in place for 9ct, 14ct, 18ct, 22ct and “fine
gold/silver/platinum” (999), which are clearly traditional alloys,
but all of the new alloys, like 500 palladium or 850 platinum exist
to give flexibility for alloys of different working properties,
rather than because of any traditionof alloys with that fineness.
You will never see a carat mark as part of a hallmark on modern
items, although some manufacturers do put carat or fine ness stamps
on items for their own stock management.
