Hello Jean, In answer to your question I have had agates that have 'faded' over the years especially those exposed to bright sunlight. There have been other memebers in the Club that this has occurred to also. However I've never heard of jade fading or bleaching but believe that it may occur. I have passed your question round some of the more knowledgeable members and if any definitive responce is forthcoming I'll post it on to you. I hope what little information I have replied with so far goes someway to answering your question. A. McCreadie (Treasurer) Scottish Mineral & Lapidary Club www.lapidary.org.uk
