Brandt,

If you used anything with chlorine in the reaction, I would have to say you are seeing silver chloride which starts out white and changes to purple in the sunlight. Silver nitrate plus chlorine will produce silver chloirde which looks like a white cottage cheese (clumpy)that settles to the bottom. When exposed to light it changes to purple then gray.

What did you dissolve them with?

Homemade nitric or the Technical grade stuff?

Did you use distilled water or tap water?

54% nitric with distilled water

The purple could be colloidal gold. This occurs in a Cu or Ag alloy containing gold, when the gold is about 20%, or less.

Are the beads plating media? If not, what is their source?

Came from using silver in an assay flux.
