Magnesite, a frequently encountered mineral in the calcite group, is composed of magnesium carbonate (MgCO3) and forms primarily through the alteration of magnesium-rich rocks. Often manifesting in hues ranging from white to lilac-rose, magnesite exhibits a Mohs hardness of 3.5 to 4.5, underscoring its relatively soft nature. Its porous structure, a hallmark of its mineralogical identity, allows it to be dyed, thereby mimicking more prized gemstones such as turquoise, which enhances its desirability in the domain of jewelry.
