No, a tiny bit of reaction, in certain spots.
And on/in the black viens, there are little colored, gems..
Green and red hues.
structure is maliable. .
I dunked a small one in acid..
It just got shiney, bright yellow,in spots.
Then , went back to looking oxidized .
They have gold branches,
Under a loop..
And many straight soft edge cuts.
All over..
I live on the Indian river.
They have been digging it up.
They just floated up, after yesterday's tropical storm.
Shiny in the water.
They all look the same
Black veins.
