I ran into many more blue to green sliders in the collection than I ever expected, but the variety that is really spooking me is the unstable pink/red to peach/orange. This is another gemstone that does not agree with the label (peach) on the storage box and my eye which says that it is a pink under my yellowish light source. I have seen some of this variety on the inter net which included a few pages from Thailand, but I have read nothing about it. I do know from the work I did with Laurellite, that the eye/mind has evolved to maintain color consistency. This means that an orange will stay orange even in the changing light of a full day. It also means the response of the eye/mind to differences in color intensity can cause color change.
This attractive gemstone has a nice medium pastel look and appears to be eye clean. It has fine crystal and weighs 2.46 carats. A really nice middle of the road trooper except for the pesky color shifting.
