pyrite is an abundant sulfide mineral that despite some similarities can easily be distinguished from actual gold by its crystal form (typically cuboidal) and being much harder whereas gold is soft and malleable

Sugar Quartz With Calcite Wulfenite and Mimetite it is instead formally knownOne of the most common minerals on earth, Calcite is a form of Calcium Carbonate and is one of the primary components in limestone. It is found in a vast array of forms, from prismatic crystals to fibrous wisps. Calcite is clear naturally but it can be found in a variety of brilliant colors due to the presence of chemical impurities during formation. These large, showy specimens contain chunky calcite crystals of exceptional shape draped within a
