Singapore Aspial's Purple Gold

Jewelry Discussion
#1

I am just about to leave Budapest and catching up with emails. While
on the way here we stopped at Singapore for a short time - just
enough for me to discover the purple gold in a shop called Aspial.
While I can’t get on to the site right now I am hoping that by the
time you read this there will be no problem. aspial.com The catalogue
I got has a TM after Purple Gold, I’m not sure how world wide that
would be. All the purple gold is ‘set’ in white gold with diamonds.

It is hard to tell from the images on the website but it looks less
saturated in color than the purple gold I have seen before. The
website says they have a proprietary formulation for their purple
gold

    The breakthrough was in finding a way to produce Purple Gold
that is strong yet soft enough to withstand shaping into jewellery
pieces, at the same time being less reactive to contaminants.

I would like to see some in person. If it really is a formable alloy
then they have quite a interesting piece of metallurgy. I assume it
is a patented alloy.

This purple gold is extremely well known in that part of the world.
I think it was invented at Singapore Polytechnic and then licensed to
Aspal from what I read.

According to a 2002 Gulf News article:

  "The man who holds the credit for its invention is Loh Peng
  Chum of Singapore. He derived this shade of royalty by putting
  the yellow garish metal to the ultimate test, at 10000C
  through a sophisticated manufacturing process known as plasma
  vacuum pressure. The final product is composed of 80 per cent
  gold and 20 per cent precious metals. Purple gold has been
  patented under "jewellery alloy compositions" and also has been
  approved by the World Gold Council."

don’t quote me on this, but I think I read somewhere that purple gold
contains aluminium, the other 20% is not all precious metals
