Inlay gold on platinum band


#1

What are the steps to inlay gold on the inside of a platinum band?
The entire circumference.

Can the inlayed gold, where the crystal structure technique is used
(heated to ‘grow’ the crystals then etched in aqua regia), be
applied to rose golds? If so what karat/alloy composition?

Thanks in advance,
Eric

I wrote an article about fusing 22k gold into a platinum band 10-12
years ago. It is fairly easy to do, since gold melts at a
considerably lower temperature than platinum. 22k works nicely since
there is little oxidation. The color contrast is quite nice as well.

I didn’t answer yesterday because I don’t know about the acid
texture that was asked about, but you just cut your inlay space, get
a gold wire and melt it into the space. Then you file it down, and
remelt if there’s any porosity. Easy - great thing about working in
platinum…
