Goldline

Goldline is the name given to varieties of quartz with lines of gold-colored goethite (an iron oxide impurity) embedded in the matrix. It is sometimes called cacoxenite. The quartz can be citrine, amethyst, or smoky quartz and is tumbled or cut cabochon. Specimens can be two to three inches (five to eight centimeters) in diameter with the bright yellow strands of goethite running in parallel lines. Sometimes large pieces are found, but these are subject to breakage during travel. A typical stone has a base value of 10gp.
