** COLOR AND STREAK **
 * Pyrites colors can consist of a pale gold-yellow color. As it tarnishes it gets darker and iridescent.
 * The colors have nothing to do with the streak of pyrite. While the colors consist of golds and yellows, the streak test reveals the difference between pyrite and gold.
 * Gold leaves a gold streak when tested on a streak plate
 * Pyrite leaves a greenish-black to brownish-black streak behind.
