Making oxidation lighter or darker

One thing that attracted me to the midgard serpent and viking beads was the matching pattern. But the oxidation on my midgard serpent is very dark, while my viking is quite light and on one side there is hardly any oxidation. I think something in between would be ideal, and I'd love to be able to have them match more. To me, the oxidation on the midgard serpent almost looks like it has been painted on, and I don't like that the oxidation is shiny either. I don't know if it's related, but the metal colour of the two beads looks a bit different too (midgard is more grey, viking is more yellow/brown - both were from Perlen).



I can't reach into the dark bits of the midgard serpent to polish it. I've thought about using a silver polishing solution, or doing the bicarb soda and aluminium foil silver cleaning method, but that will probably make it too light, and I don't know if I'll be able to get it darker again.

Today I tried to darken the oxidation of the viking using a broken up boiled egg yolk in a container with the bead. It's possibly a bit darker, but still much lighter than the midgard serpent. I'd really like to make the midgard serpent lighter, but I'm worried about ruining it. Does anyone have any experience with this? I'd love to hear your thoughts.

I know I'm being really picky, and I don't mean to whinge I'm just curious as to whether there's something relatively simple I could do.

If you take it to a silversmith they'll likely remove the 'painted oxidation' and reoxidize both in "liver of sulphur" simultaneously to ensure a similar look. Oxidation applied that way gives silver jewelry that true antiqued look like the old TB silvers have.

The viking bead may have been partly deoxidized before. I've done it myself too with a bead and recognize the color change, can't imagine TB would use different silver alloys. Reoxidizing would deal with the color difference as well.
