Black Onyx is a popular gemstone that has been prized for its beauty and durability since ancient times. It is a form of chalcedony, which is a mineral in the quartz family and is known for its sleek, smooth appearance and deep black colour. In this blog, we will explore the scientific properties of black onyx and the geological processes that form this striking gemstone.
How Does Black Onyx Form?
Geologically, black onyx is formed through a process of crystallisation. Quartz crystals, which are made up of silicon and oxygen atoms, are the primary component of black onyx. These crystals form in cavities within volcanic rocks or in sedimentary rocks that have been altered by heat and pressure. As water flows through these cavities, it dissolves minerals and deposits them within the quartz crystals. This process, known as precipitation, can create a wide range of different colours and patterns within the quartz, including the deep black of black onyx.
Why Is Black Onyx Black?
The colour of black onyx is the result of the presence of iron and carbon within the mineral. Iron impurities create the dark colour while carbon is responsible for the blackness. The amount of iron and carbon present in the mineral can vary, leading to different shades of black and even brown or grey tones. Black onyx may also be dyed or treated to enhance its colour or mask imperfections, so it is important to purchase this gemstone from a reputable source that can verify its authenticity and natural properties.
The Physical Properties of Black Onyx.
In addition to its striking appearance, black onyx has a number of interesting physical and metaphysical properties. It is a hard, durable stone that rates between 6.5 and 7 on the Mohs scale of mineral hardness, making it a popular choice for jewellery and other decorative objects. Black onyx is also believed to have metaphysical properties that make it useful for meditation, grounding and protection. In some traditions, it is associated with the root chakra and is thought to promote feelings of safety and stability.
Industrial Applications of Black Onyx.
In terms of practical applications, black onyx has a number of industrial uses. It is sometimes used as a cutting tool because its hardness and durability make it an effective material for shaping other stones and metals. Black onyx is also used in the production of electronic equipment such as high-performance speakers and microphones. It is a popular material for these applications because of its ability to absorb sound and vibrations which can improve the quality of the sound produced.
