Emeralds are precious gemstones known for their vivid green color and rarity. Emeralds belong to the beryl mineral family, with a chemical composition of beryllium aluminum silicate. The green color is caused by trace amounts of chromium and sometimes vanadium....

Ruby, like other gemstones such as sapphire and emerald, is found in geological formations known as gem deposits or gem-bearing rocks. Rubies are precious gemstones composed of corundum (aluminum oxide) with trace amounts of chromium, which give them their characteristic...

Mica ore refers to natural mineral deposits that primarily contain mica, a group of sheet silicate minerals. Mica minerals are known for their perfect cleavage, flexibility, and resilience to heat and electricity. Mica minerals occur in igneous, metamorphic, and sedimentary...

Pink salt, often referred to as Himalayan pink salt, is a type of rock salt that is mined from the Punjab region of Pakistan, specifically from the Khewra Salt Mine, which is one of the largest and oldest salt mines...

Granite is an igneous rock composed of minerals such as quartz, feldspar, and mica, rather than a metallic mineral. However, it is often extracted from quarries and processed for various applications in a manner similar to metallic ores. Granite is...

Coal is not typically referred to as “ore” in the traditional sense, as it is not a mineral but rather a combustible black or brownish-black sedimentary rock composed mostly of carbon and hydrocarbons. However, it is often mined and processed...

Gypsum ore refers to natural deposits of the mineral gypsum, which is a soft sulfate mineral composed of calcium sulfate dihydrate. Gypsum ore is primarily composed of calcium sulfate dihydrate, which is a white or colorless mineral. It may also...

Soapstone, also known as steatite or soaprock, is a metamorphic rock composed primarily of talc with varying amounts of other minerals like chlorite, pyroxenes, micas, amphiboles, and carbonates. Talc is the main constituent of soapstone, typically comprising 30% to 80%...

Quartz ore is composed of silicon dioxide (SiO2). It may also contain trace amounts of other elements such as aluminum, iron, titanium, and lithium, which can impart different colors and properties to the quartz. Quartz occurs in a wide range...

Marble is a metamorphic rock that forms from the recrystallization of limestone under high pressure and temperature conditions deep within the Earth’s crust. Marble primarily consists of calcite or dolomite crystals, which give it its characteristic texture and appearance. Marble...
