Sizing: The crystal chips often have one side that is at least 5 mm in one dimension. Crystal chip bracelets are small pieces of crystal that have been tumbled until smooth, and then strung together on elastic. Fluorite is a wonderful crystal due to its great variety of colouring of purple, green, white and clear. These fluorite chip bracelets from a distance do tend to appear more purple, but do contain the other colours too to different degrees. A good quality bracelet.
