How are cleaning these? I also have some crystal gold but it is ugly right now.

 If your specimen has quartz I would try Whink that has a small concentration of hydrofluoric acid for somewhat more aggressive cleaning of the gold, removing iron oxides and dissolving some of the quartz. If you use these two methods it will take time to see any satisfactory results, so be patience.  If you have some hydrofluoric acid in a higher concentration (48% strength or more) you will have faster results and would need to monitor closely so you don't destroy the specimen. But be extremely careful when using any type of hydrofluoric acid in any form, the acid is deadly and I mean deadly, you better know what you are doing! Finally soak the specimen in baking soda if you use any of the cleaning methods above. There are other methods that can be used to also give a wow look, but I would need to studying the specimen first hand on what would be the best course of action to take. The specimens that we find has shale as the host rock and I can use other types of acids to clean them.

Holy Grails Glenn, Those pieces of art are most certainly wall hangers.  CO is one of the stated that I need to go and find a couple, so I check off my list "Been there Dug That" along with WY and the Dakotas.  I don't have many wire gold pieces as you know they are quite fragile and easily break or smash.  Here is one of my bigger ones.  Thanks for sharing some beautiful gold.
