Phantom quartz, also known as "Ghost Quartz," is a unique type of quartz that exhibits visible inner, ghost-like silhouettes of previous growth stages, formed when mineral deposits (chlorite, iron oxide, etc.) halt and then resume the crystal's development. Often sourced from Brazil, this stone is valued for its distinctive, layered, or pyramidal internal inclusions, which can be found in clear, white, smoky, or amethyst varieties.
