Ok , there was this thread a while back about blue gold.
Anyway, There’s this company in South Africa, called Mintec. They
had an article a month or so ago in SA Jeweller, about a mix of
alimimium and fine gold-- to 18k.t-- and there was a picture of
it in facetted form.
I ordered it from them and they made me a button, about 10mm or
so in diameter. It is a nice colour, sort of looks like purple
Haematite. It’s got a sort of amythist-ish colour in incadecent
light, and a cooler colour in neon light .( my opinion) The
colour is pure all the way through.
It cost me ±R100/ gram.(16US) I carved it into a flower with an
emerald inlay. It drills with Tungsten-carbide bits, but as with
everything, diamond bits work best. I used Silicone rubber wheels
to finish up to rouge, and after it was rouged up it came to a
When you work it it can make small chips, so a soft touch is
wanted. The powder that comes off looks and feels like that
eyeshadow stuff that my girlfriend uses.
I didn’t heat it up, in fact, I treated like a Tourmaline, in
all aspects, since this was a brand new material for me, and
maybe it had inherited tourmalines Bad Moods, as they
sometimes have. It didn’t. It works like soft opal and from my
experience I would put it at ± 4 on the Mohs scale.
It is known as an intermetallic compound.? What’s that? I thought
that alliminium is a metal? How can something that is as soft as
aliminium or gold mix to become so hard that it blunts an
ordinary drill? Strange world!
Anyway For the record, I also ordered The Mysterious Blue Gold
.(Indium/Gold ) It’s not blue–I mean BLUE-- It’s the same as
green gold is not apple green. It’s green after a couple of
beers, yes, but not green.
