Nickel-free Black finish for jewelry
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.

The right way to go:
1) Use a white bright Bronze undercoat.
2) Follow with a choice of Ni Free black plated topcoats .
