Painted with color changing pigment, she transforms from a streaky purple into beautiful baby blue when exposed to warmer temperatures. Comes with carb hole. Note: Each piece is unique in form but still holds the likeness of their quartz family. They are roughly 8-12cm long and average 55-100grams.
