Did you precipitate the powder yourself?If so,what method did you use to precipitate? Did you wash the powder before melting it? And if so did you use nitric? Copper nitrate crystals are blue,I am just wondering if that had anything to do with it.
But yes it does have a very beautiful look to it.

The source of your solution may give the answer to your question. The button looks to be more like a karat alloy than fine gold so if it's a jewellers stripping solution the colour in the flux might be from copper that strips along with the gold, it's also possible that not all the cyanide was removed from the powder and that colours your flux depending on the other metals in the salts remaining.

Typically, what is done is to digest the zinc away with nitric acid. The oxidizing nature of the nitric acid will destroy some of the cyanide and be all that much "safer".
goldsilverpro posted excellent advice on recovering the gold, just search it up.

It's pretty straightforward. Just rinse the zinc precipitate as much as possible. If you're really concerned, add an excess of strong bleach.
