Enchanting pair of Onyx Sphere and Green smithsonite freeform on custom stand. Onyx is a type of gemstone that belongs to the cryptocrystalline form of quartz. It typically forms in the cavities of igneous rocks, especially volcanic lava flows, where silica-rich fluids deposit layers of quartz over time. This process creates the characteristic banded appearance that onyx is known for, with alternating bands of different colors. While black and white banded onyx is the most common, it can also occur in shades of brown, red, green, or other colors. Green Smithsonite, also known as green zinc spar, is a mineral that belongs to the carbonate mineral group. It is a secondary mineral that forms as a result of the weathering and oxidation of primary zinc ore deposits. Smithsonite typically occurs in a variety of colors, including green, blue, pink, yellow, and brown. The green color in smithsonite is often attributed to the presence of traces of copper. It is a relatively soft mineral, with a hardness of 4 to 4.5 on the Mohs scale, making it susceptible to scratching.
