This crystal has caused much confusion, and the name keeps swapping. I think we are now settled on Scheelite in Calcite, although I would still call it Lapis Lace (Onyx). The confusion echoes the characteristic of labels and names not being important, it is more important to experience. What we call it does not change its properties. It is one of the most calming stones, and helps us to ride the waves like a surfer. Try one on your third eye or under your pillow at night.
