I'm with BJ,it's very hard to photograph real pink marbles,it turns out to be amber.
I've tried it and with a lot of tricks i succeded.
BTW Germany has also made pink 2 seam slags.
Here's a German one,the 2 pic- are the same marble,the first pic- is the real color,
made with tricks,don't ask me how,i forgot.
Don't know if Roger's marble CAC or German is.
