Hello,
I have some vintage czech beads never used. I have found them in the genuine box but they have white stain on it. Do these white stains come from the mold?
You will see a picture of these beads here: ECHEVEAU ANCIEN DE 1200 BOHEMES TON GRENAT Made in Czechoslovakia http://r.ebay.com/GSttKf

Many thanks for your help

Lucien
