"blackening" white gold

Well, after spending days searching for jewelry at last:
nirvana3Dorchid! My opening on orchid: a problem… A customer of mine
requested white gold, blackened, as seen with different (italian)
designers (mostly combined with black diamonds). All I could get hold
of were webshots. The surface looks metallic, a slightly darkened
metal (white gold) surface. It does not look like a black skin or
oxide. I have not a clue and would be very thankful for hints. My
speciality is carving wax, but i do go through to the finished product occasionally.

Try my favorite place. Any time I get stumpted, they can usually come
up with an answer for me. You can find them at www,riogrande.com/
they also offer 3 catalogs, all of which are FREE. Good luck, and let
us know what you find out. sounds interesting

and solvent. But I hate chemicals!! and have never used it. if it
smalls bad I would give it away . But thats me!!! I would try copper
flashing with old pickle and Iron. Then try some other way to blacking
it, I love liver of sulfur or black max. Then buff off where you
don’t want it. I have never done this my self so I would try with
scrape first and play.

There is a Plating solution known as “Black Rhodium” which is used to
give this surface finish. It works exactly the same as “White” Rhodium
Plating—BUT—it is nowhere as durable or as long lasting, so only
use on pave’ or protected area’s. It is not Black black but more of a
"gun metal" Bluing. I use it quite regularly and have had no problems
with it. It is manufactured by Hereaus (Spelling) in Germany.

I wonder if the black on the white gold could be black rhodium
plating? I have seen the solution in the Rio Grande catalog and
thought about trying it out. I think it could be a very beautiful
contrast.

And it is called Rothenium.It looks elegant specially around diamonds.
