Nickel-free Black finish for jewelry

Q. G'day all,

We currently produce a bright black finish for fashion jewelry using bright nickel with a thin coat of "Electroblack" to produce the black finish. Problem is we have been asked to produce the same finish "nickel-free" for the European market.

Any ideas on what we could use to produce this finish as we understand that the "Electroblack" is a tin-nickel deposit and would not be acceptable. (for those who do not recognize the "Electroblack" process it is produced by a US Company and is a hot cyanide electrolytic process that works fine except we understand the deposit contains nickel)

Anything anyone could contribute would be appreciated.

A. The right way to go:

1) Use a white bright Bronze undercoat.
2) Follow with a choice of Ni Free black plated topcoats .
- Black Ruthenium
- Black Gold
- Black Rhodium [adv: black rhodium plating solution on eBay or Amazon [affil link]
