What is Garnet Crystal?

Garnet is a group of natural silicate minerals known for their brilliant color, hardness, and wide use in both jewelry and industrial applications.

Garnet is often used as the abrasive material in sharpening stones and sandpapers because of its durability and angular shape. If a tool is labeled as garnet grit or garnet sharpening stone, it means the abrasive component is crushed garnet — excellent for smoothing and honing blades.
