The chemical formula of mineral Rhodizite is indicated by (K,Cs)Be4Al4(B,Be)12O28 or Potassium Cesium Beryllium Aluminum Borate. Rhodizite is actually a Carbonate mineral. Rhodizite is most commonly used as mineral specimen and it is also sometimes cut for gemstone purposes. Mineral Rhodizite is most commonly found exhibiting nice and interesting microscope images when viewed with the aid of petrographic polarizing light microscope used in the field of optical mineralogy. Rhodizite is a rare potassium cesium beryllium aluminum borate mineral. Just its chemistry gives away its rarity. Mineral Rhodizite is remarkably known not only for its chemistry but also for its bright adamantine luster in reflected light of petrographic polarizing microscopes for mineralogists as well as its high degree of hardness. Both properties actually lend themselves well to the fashioning of a gemstone. Mineral Rhodizite is too rare and it generally lacks good color to be used often as a gemstone. It is also very interesting to note that mineral Rhodizite has a very similar sound name as the silicate Rhodonite, the carbonate rhodochrosite and the silicate rhodesite. Do not confuse Rhodizite for these similar sounding minerals because they may sound alike but they are actually very different minerals.

 

            Mineral Rhodizite is most commonly found colorless to white or gray and also with pale tints of yellow that could appear more fascinating when viewed with the aid of polarizing microscopes for mineralogists. Rhodizite is also usually found showing vitreous to adamantine or silky luster when viewed in reflected light of polarized microscopes for mineralogists. Most crystals of mineral Rhodizite are found transparent to translucent in appearance. Mineral Rhodizite is also known to crystallize in the isometric system of crystal formation. In optical mineralogy, this isometric crystal system comprises crystals having three axes, all of which are perpendicular to one another and all are found equal in lengths.

 

            The crystal habits of the mineral Rhodizite as described in the field of optical mineralogy usually include dodecahedral crystals and embedded grains that could appear more interesting when viewed with the aid of petrographic polarizing microscopes. Rhodizite has absent cleavage even when it is closely evaluated using the polarized microscopes for mineralogists. The hardness measure of mineral Rhodizite when specimen is evaluated using the Mohs scale method is usually 8. Rhodizite is also most commonly found leaving a white steak when specimen sample is rubbed on a white porcelain streak. The specific gravity measure of the mineral Rhodizite is approximately 3.3 to 3.4 grams per cubic centimeters, which is considered slightly above average for translucent minerals. The index of refraction shown by mineral Rhodizite is usually 1.69. Rhodizite is also usually associated with the red tourmaline elbaite. The best field indicators of mineral Rhodizite usually include color, crystal habit, locality, associations, lack of cleavage and the unusually high degree of hardness. Rhodizite specimens come from only a few areas in Ural Mountains and Madagascar.
