Chrysanthemum stone, sometimes called "flower stone," is a stone "flower" produced millions of years ago due to geological movement and natural formation in the rock.[1] The stone's pattern resembles the chrysanthemum flower. The flower is milky white and grain is clear.
Chrysanthemum stone is generally dark-gray or black, and does not contain radioactive elements, so it has a high collection value. Although the composition of chrysanthemum stone itself is not very rare, the formation is uncommon, so the stone is listed as a gem.[2]
Vancouver Island in British Columbia Canada, is a well known place to find Flower Stone, mainly on the east coast! It was once commercially mined on Texada island which is off the east coast of Vancouver Island, but there is now a moratorium on mining there, although rock hounds may still hand pick it. Walking on the beach at low tide on either island flower stone can be found, along with Dalasite and Red Jasper.
