After using Baldwin’s Patina on a cleaned Copper/Argentium Silver
Mokume Gane ring, I noticed that just after a day or two of wear
that most of the dark patination on the copper I achieved begins to
fade into a sort of caramel-brown color.
Is there anything I can do to keep the dark patina on the copper?

Don’t wear it. There are no patinas for copper that will stand up to
ring wear. Secon problem, the copper is going to dissolve due to
galvanic corrosion. How fast will depend on a whole fist full of
variables but if you wear it every day in a year or so you will see
major loss of the copper.

Would the addition of 5% gold in that copper reduce the degradation?

Shakudo, 95% copper 5% gold will self patinate on the hand but it
will also continue to dissolve due to electrolysis so it is not
really a solution for the long term.

That is a bit disappointing.
I suppose it’s okay for things that don’t come into contact with
skin or water, like a tsuba or a pot.
Wonder is a sacrificial anode would do the trick? Just a small piece
of metal that could be replaced when it wears out.
The only thing I can think of that will give you a long lasting
protective coating is to plate the finished piece with legor’s Kliar
nano ceramic electro plating. They have a clear coating that is very
good. It also has a added advantage of making the piece hydro
allergenic. I do not know how long it will last on a ring but my
test on things like money clips have been very good.

Kliar is a interesting new product and the test results I have seen
would indicate that on anything but rings it would be a reasonable
coating to prevent tarnish or corrosion. But there is just not any
coating that can stand up to the daily abuse a ring sees for very
long.
I agree with James here. In the day I have seen nickel plating over
silver and then rhodium. try sizing this type of ring. saw in coming
from Mervyn’s. what a nightmare. They just couldn’t understand why it
cost them so much to size these rings. No matter what kind of finish
you put on a ring it wears off one way or another. brush or stone
finishes where down to burnishing and polished rings get scratched.
Rhodium rings lose their rhodium and gold plating wears off the same.
There are ways to make it stay longer but not forever.
