Shapeshifter. 

Or color shifter. Such a wild stone! From a distance it looks like a nice pale green moss aquamarine. But then you get closer. And then you change the light. I shot some of these photos outside and the stone looked far more blue to me, when indoors I think it looks like a pale sage green. Neither of these states changes the rainbows, which is my favorite part. 

Set in sterling with gold-filled accents. 

16-18 inches in length, adjustable.
