FluoriteIn other words, the typical habit of fluorite is a cube and the colour zones are often in a cubic arrangement. The effect is similar to phantomed crystals, that appear to have crystals within crystals that are of differing colours. A fluorite crystal could have a clear outer zone allowing a cube of purple fluorite to be seen inside.
