Fluorite is a luminous, soft and glassy stone, sometimes referred to as "the most colorful mineral in the world." It is one of the most sought-after minerals among gem and mineral collectors, second only to Quartz. The term "fluorescent" was inspired by Fluorite, one of the first fluorescent minerals ever studied. It is frequently fluorescent under ultraviolet light, and this phenomenon is thought to be due to impurities of yttrium or organic matter within the crystal lattice.
That notwithstanding - it is yummy shades from pale mint to emerald to eggplant to soft lilac. The stone can crack with sharp blows - we suggest not dropping them, or wearing them as bracelets if you are a hard-core typist or heavy metal musician.
