THE VAULT PRECIOUS JEWELS OFFERS A RARE 100% NATURAL COLOUR IN SOUTH AFRICA

        Fluorite, discovered as early as 1530, is considered to be one of most popular minerals in the world among gem and mineral collectors, second only to quartz. It is often referred to as ' the most colorful mineral in the world ' owing to its variety of brilliant colors.  In 1852, the phenomenon of 'fluorescence' was named after fluorite, since it was one of the first fluorescent minerals studied. Fluorite is frequently fluorescent under ultraviolet UV light. The fluorescence is thought to be due to impurities of yttrium or other types of organic matter within the crystal lattice. The color of visible light emitted when a sample of fluorite is fluorescing appears to be highly dependent on where the specimen was collected. Fluorescent colors of fluorite are extremely variable. They include blue, yellow, green, red, white and purple. Some specimens have the added effect of simultaneously exhibiting different colors under long and short wave UV light.         PICTURE IS ENLARGED     Gem type:FLUORITE   SHAPE OVAL FACET TREATMENT NATURAL WEIGHT 4.42ct ORIGIN GERMANY DIMENSIONS 11x9mm CLARITY VVS COLOUR PEACOCK BLUE TO PURPLY RED COLOUR SHIFTING HARDNESS 4 LUSTRE ADAMANTINE QUANTITY 1                                       GIA CLARITY
