A terp pearl, also known as a dab pearl or terp ball, is a small spherical or bead-shaped accessory used in conjunction with dab rigs or vaporizers for consuming concentrates, such as wax, shatter, or budder.
Terp pearls are typically made from materials like quartz, ceramic, or ruby, and they are placed inside the heating chamber of a dab rig. When the concentrate is heated, the terp pearl spins or moves around within the chamber, creating a stirring or agitation effect.
