Goldline

Goldline is the name given to quartz with lines of gold-colored goethite (a rustlike impurity) imbedded in it, sometimes called cacoxenite. The native quartz stone can be citrine, amethyst, or smoky quartz--the goethite appears as brilliant yellow or gold fibers or tufts that run in parallel lines. Goldline is tumbled or cut cabochon, and usually occurs naturally in pieces two to three inches (five to eight centimeters) in diameter. Sometimes larger slabs are found, but these rarely survive travel unbroken. A typical stone has a base value of 10gp.
