Kim Bruun Rough Rock Total Posts: 31 Last Post: 8/1/2008 Member Since: 5/18/2008	I am looking into morganite and purple scapolite, and I am wondering if these are susceptible to fading in the sunlight, like kunzite infamously does? I would very much like to know which clear colored stones you should generally avoid if you don't want to risk your stones fading in the sunlight, but I am particularly interested in morganite and purple scapolite. I am hoping some of the experts here can be of help. Thanks in advance!

From what I have managed to find out - so may not be completely accurate: Morganite - the unheated stuff can fade a bit in strong sunlight, but the heated morganites (which seem to be rather a lot of them) have permanent colour. Scapolite - I can't find anything on the violet type fading, only the yellows. Other stones to avoid: kunzite, some acquamarine. Personally, I'd avoid leaving any colour stone baking in the sun for long!

It is such a pretty stone, but totally uninteresting when it is almost colorless. I've read that amethyst and rose quartz can also fade in the sun. I also found this interesting article on blue zircon: http://www.suwagem.com/dictionary/quality/book2-20/1.html So a heated blue zircon that has faded in the sun wil regain its color if kept in a dark place for a few days?

Rubies don't feature on my current radar. I only like the really great one's and don't like anything with even a hint of opacity. Hence, they are way out of my price range. However, I have a long list of wants before I start to feel that my collection will be incomplete without one!
