While pure fluorite is colorless and transparent under both visible and ultraviolet light, impurities often impart vibrant colors, making it a popular choice for ornamental and lapidary applications. In industrial contexts, fluorite serves as a flux in smelting processes and is utilized in the manufacture of specific glasses and enamels. The highest purity grades of fluorite are essential for producing fluoride, which is a key component in the production of hydrofluoric acid, a precursor for many fluorine-containing fine chemicals. Additionally, optically clear fluorite exhibits unique properties, such as anomalous partial dispersion, which allows its refractive index to vary with light wavelength, making it advantageous for crafting apochromatic lenses and valuable in photographic optics. Fluorite's optical characteristics extend to the far-ultraviolet and mid-infrared ranges, where traditional glasses are ineffective, and it is noted for its low dispersion and high refractive index relative to its density.\u003cbr\u003e\u003c\/p\u003e","brand":"Crystals2Collect A.C.N 651.525.727 Pty Ltd","offers":[{"title":"70 90 68 200 \/ BROKEN HILL, NSW, AUSTRALIA \/ 899","offer_id":49740004360468,"sku":"899","price":245.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0706\/2047\/9764\/files\/20250530_201902.jpg?v=1779190543"},{"product_id":"creedite-4-crystals-minerals-rocks-crystals2collect","title":"CREEDITE, Monakoff Mine Cloncurry Cloncurry Shire Queensland Australia (LARGE CABINET)","description":"\u003cp\u003e\u003cstrong\u003eCreedite\u003c\/strong\u003e is a rare mineral composed of calcium, aluminum, sulfate, and fluorine, represented by the formula Ca3Al2SO4(F,OH)10·2(H2O).

Penetration twins are a common occurrence. Despite its attractive color, cuprite is seldom utilized in jewelry due to its relatively low Mohs hardness of 3.5 to 4. It possesses a high specific gravity of 6.1, exhibits imperfect cleavage, and is brittle with a conchoidal fracture. The mineral's luster ranges from sub-metallic to brilliant adamantine.

Beudant introduced the name céruse, while the current designation, cerussite, was established by W. Haidinger in 1845. Historically, miners referred to it as lead-spar or white-lead-ore. Cerussite crystallizes in the orthorhombic system and shares isomorphism with aragonite, often exhibiting twinning that results in pseudo-hexagonal forms. Typically, three crystals are twinned on two prism faces, creating six-rayed stellate groups that intersect at nearly 60-degree angles. The crystals are commonly bright and smooth, but the mineral can also appear in compact granular or fibrous forms, usually colorless or white, with occasional grey or greenish hues. It ranges from transparent to translucent and possesses an adamantine luster, with a Mohs hardness of 3 to 3.75 and a specific gravity of 6.5. A variant known as iglesiasite, which contains 7% zinc carbonate replacing lead carbonate, is found in Sardinia. Cerussite is easily identifiable by its distinctive twinning, adamantine luster, and high specific gravity, and it effervesces when dissolved in dilute nitric acid.
