These are oxidized metal grains. The oxidation color is bluish and
most
closely resembles blueberries, though I am somewhat color blind.

Any idea what this metal is? Could it be cobalt?

Cobalt is ferromagnetic, so unless it is fully oxidized, it would
be
magnetic.

So it is not cobalt... no attraction to magnet...


Perhaps the light blue color came from oxidized copper plating?
