Hope its not another of my silly questions. It was not answered last time.

I am posting a picture of my turquoise beads with bubbles on them. The beads are soaking in tap water. Would anyone know why this happens? Is it due to the dye, paraffin or other treatment? The beads are not expensive and from China so I guess they are not genuine. But I can't find any information on turquoise with bubbles and wonder if it happens to any other collectors turquoise ?

Hope lopacki or other turquoise collectors can comment.

Thank you so much for looking.
