Where to buy Neutral gold cyanide?

Question

Where on the Internet do you buy Neutral gold cyanide? I can't seem to find it. I need it because I am trying to replate a gold ring.

Answer 1

I don't know what you mean by "neutral" gold cyanide,  but here's a listing for AuCN on Sigma-Aldrich

Gold(I) cyanide (1)

   Linear Formula: AuCN,

   Formula Weight: 222.98,

   CAS Number: 506-65-0

254088 – 99.99% trace metals basis (Aldrich)

Product Number     Your Price-USD Available to Ship

254088-1G           $155.00 USD         07/26/2008

Answer 2

Aldrich, Alfa, and Strem supply houses will have it.  However, they will not sell these materials to a private party.  Your best bet is to visit a jeweler.  You need very little to replate and the cost of the smallest size sold, will probably be more than the ring.
