For what it's worth (not that much), google images for tin chloride, mostly white:

Aga's sample has of course been contaminated with dead moths.

The moths got in there after it became a yellow curd.

Hmm.
I put a drop of the liquid on my wedding ring, and zero reaction.
Not even a bit of discolouration.
(Half of it is stainless steel, the other 24kt gold)
Does the stannous solution only indicate Gold Ions in solution ?

Indicator of gold ions in solution only AFAIK.

I'm probably confusing it with Schwerter's solution for testing silver metal.
