I wonder if anyone can explain a strange occurrence. My
wife recently bought what appeared to be a very worn sapphire in an
18ct white gold ring for a very advantageous price. I recut the
sapphire, which turned out spectacularly well (it was native cut
and the vendor hadn't realized its quality). While the stone was
out, I submitted the ring for hallmarking. It was stamped 18K
although I expected it would probably assay at 14K, as it was not a
UK piece. I was very surprised when the assay office called me to
say that it was pure palladium. The SG of the mount confirmed this
(about 11.5; I didn't take the accent diamonds out) This is more
costly than 18K and I can't think why anyone should try to pass it
off as such.
Can anybody cast any light on this?
There was a time, when palladium was not even close as expensive as
it is today. As a matter of fact, since the northamerican standard
excluded it from the white gold ingredients, only european jewellers
used it only occasionally. So when in the early eighties gold was
$600-800 an ounce, and you could buy palladium for $50-60 this form of
cheating made eminent sense.
