— Find out how to differentiate real and fake fluorite easily Real fluorite glows under ultraviolet light Fluorite hardness is very low so there will be a lot of tiny scratches on the surface of real fluorite Fake fluorite is mostly represented by glass or plastic Fake fluorite made of glass can have bubbles and doesn t glow under UV light

Luster describes the reflection of light off a mineral s surface Mineralogists have special terms to describe luster One simple way to classify luster is based on whether the mineral is metallic or non metallic Minerals that are opaque and shiny such as pyrite have a metallic luster Minerals such as quartz have a non metallic luster
— In Comanche County and McCurtain County quartz malachite aegirine orthoclase and barite are common However if you want a more unusual gemstone such as brochantite you must go to Garvin County In the Ouachita and Wichita Mountains plenty of quartz is available Dolomite crystals are also common in Oklahoma and are mined
