The name was revised from apophyllite-(KF) to fluorapophyllite-(K) (2013). Apophyllite, whose name roughly means “to leaf apart” in Greek, is a mineral classic. It was given its name because crystals tend to peel or flake apart when they are heated due to the loss of water molecules. Although not that well-known by the general public, apophyllite is quite popular among mineral collectors. It is probably the first exotic mineral that a young collector will own after filling up on specimens of calcite, quartz, pyrite, galena, mica, fluorite, gypsum, apatite, etc, etc. After these common minerals, apophyllite seems like a real rarity and it offers so much to the collector. It has beauty, pastel colours, a bright luster, interesting well formed habits, unusual associations with other exotic minerals make it a collectable mineral indeed.
