Silica, or silicon dioxide, is one of the most abundant minerals on Earth, forming the basis of quartz, chalcedony, and opal. It occurs in a wide range of geological environments, from igneous to sedimentary formations. Silica can appear clear, milky, or coloured depending on impurities, often showing a glassy to waxy lustre. In folklore, it symbolises clarity and purity. Metaphysically, silica is believed to enhance focus, communication, and spiritual connection, promoting cleansing, harmony, and the amplification of positive energy and intention.
