Mohs hardness test When conducting the test place the unknown specimen on a table top and firmly hold it in place with one hand Then place a point of the reference specimen against a flat unmarked surface of the unknown specimen Press the reference specimen firmly against the unknown and deliberately drag it across the flat surface while pressing firmly
Streak is the color of a mineral s powder Streak is a more reliable property than color because streak does not vary You find that it can scratch fluorite or even feldspar but apatite scratches it You know then that the mineral s hardness is between 5 and 6 Note that no other mineral can scratch diamond Cleavage and Fracture
Fluorite also called fluorspar is a mineral composed of calcium fluoride Ca F is an isometric mineral with a cubic habit though octahedral and more complex isometric forms are not uncommon Cubic crystals up to 20 cm across have been found at Dalnegorsk Russia Crystal twinning is common and adds complexity to the observed crystal The name fluorite is
·Fluorite is one of the most collectible and highly sought after crystals in the world loved by mineralogists and metaphysical healers alike Its remarkable cubes are sometimes almost too perfect to believe emerging like magic treasure in matrix rock or tightly stacked cube on cube like a futuristic city in miniature
Fluorite is a calcium fluoride that crystallises in the cubic system It occurs in a wide range of attractive colours However a hardness of 4 perfect octahedral cleavage and a sensitivity to sudden changes in temperature make it difficult to facet and preserve Although rarely used in jewellery fluorite is faceted as a collector s stone
Fluorite has seven main crystal forms the most common Are the cube {100} octahedron {111} and dodecahedron {110}; these forms having fixed Miller indices ; and the tetrahexahedron {hk0} trapezohedron {h11} trisoctahedron {hhl} and hexoctahedron {hkl} less common to quite rare crystal forms having variable Miller indices Combinations of two or more of these forms are
Students plan to compare the streak colors of fluorite quartz and feldspar Strake is the color of a mineral when it is broken and powdered A mineral rubbed across an unglazed porcelain plate will sometimes leave a colored powdered streak The streak test can be used only on minerals that are softer than a porcelain plate which is less than 7

·A mineral s streak is the color it has when ground to a powder Some minerals that occur in a range of colors always have the same streak As a result streak is considered a more stable indicator than the color of the solid rock While most minerals have a white streak a few well known minerals can be identified by the color of their streak

·Rainbow Fluorite often simply referred to as Fluorite is a beautiful and highly sought after mineral known for its dazzling array of colors and unique crystal is a variety of the mineral fluorite which is composed of calcium fluoride CaF2 What sets Rainbow Fluorite apart is its distinctive multicolored appearance displaying a spectrum of hues ranging
·An even rarer property sometimes exhibited by fluorite is triboluminescence where minerals glow when they are crushed struck scratched or even rubbed in some cases The minerals contain chemical bonds that emit light when mechanical energy is applied to them Fluorite is a common vein mineral associated with mineral deposits
Streak examines the color of a powdered mineral and can be seen when a mineral sample is scratched or scraped on an unglazed porcelain streak plate A paper page in a field notebook may also be used for the streak of some minerals Lower image shows fluorescence of fluorite under UV light One of the most interesting special mineral

·A good way to tell the difference between minerals like quartz and fluorite is by testing their hardness Fluorite hardness on the Mohs scale is a 4 while quartz is a 7 Scratching the surface of stones with other minerals or objects is an easy way to determine what type of stones they are
