Faden quartz from Colombia is a unique variety of quartz known for its distinctive "thread-like" inclusion that runs through the crystal. The name "faden" comes from the German word for "thread," which describes the thin, white line inside the quartz. This formation occurs when the crystal experiences stress or growth interruptions, causing it to heal and reform multiple times. Colombian faden quartz is often highly transparent with well-defined internal threads, making it a favorite among collectors. It is believed to have powerful metaphysical properties, symbolizing strength, healing, and spiritual growth.
