Very unusual and interesting gold specimen, is this a pseudomorph?
And again a beautiful Oppu Mine rhodo - I love it!

Thanks Tobi!
The gold isn't a pseudomorph. I don't think that it is a true gold wire, but a series of stacked crystals forming a column that bends around the matrix.

Thanks Sante!
The coloring does obscure any possible faden line.

Hi, Am.
Unfortunately, I know the problem. I've a similar specimen from the same locality with chlorite inclusions, where you can barely recognize the string.
However, in your wonderful specimen the unmistakable shape is very indicative.
Warm greetings.
Sante
