Minerals: Dickite
With a composition of Al2Si2O5(OH)4, dickite is a sillicate mineral named after the Scottish metallurgical chemist Allan Brugh Dick, who first conducted experiments on the clay mineral (though he did not realize that the kaolin he was studying was actually more than one distinct mineral).
Dickite occurs with other clay minerals (and is often associated with quartz as well) in locations around the world and, as such, is hard to distinguish. X-ray diffraction is typically used to confirm the presence of dickite. It is a monoclinic crystal that is white in color (any other colors of dickite come from impurities). It has a Mohs hardness of between 1.5 and 2.

💙💚 Love this “layer cake” specimen of Azurite, Malachite, Dickite, and matrix from the famous Milpillas Mine, Mexico! Swipe through photos and see a video of the specimen in action. This is truly a unique piece—self standing as shown, this cluster combines contrasting layers of material, including ultramarine azurite, verdant green malachite, and white dickite matrix. To me, it looks like a rich dessert or a topographic map, with many contrasting textures and colors. Large Azurite crystals strike up from one of the layers, displaying beautiful structure, minor damage, and the deepest midnight blue color. Many of the crystals in that layer show beautiful alteration from deep blue to green malachite, as the secondary mineral pseudomorphs the original azurite. Contrasting colors and a unique shape make this specimen truly one of a kind—your chance to own a specimen from this famous mine for a great price! 💚 $118 shipped US; dm to claim, or visit it at PhenomenalGems.Etsy.com! 💙 #azurite #malachite #dickite #milpillas #mexico #mexicanbeauty #minerals #rocks #rocksandminerals #mineralspecimen #collection #goodvibes #boho #hippie #naturelovers #crystalhealing #phenomenalgems #etsy #etsyshop #etsycrystals https://www.instagram.com/p/Bu_0uwXn7xM/?utm_source=ig_tumblr_share&igshid=115owieiicflx
