Mineral Minute - Episode 1: Amethyst

Watch this short video as we spend 60-seconds exploring everyone's favorite purple variety of quartz: Amethyst, right here on Mineral Minute:
Today’s Mineral: Amethyst

Amethyst is a colorful variety of the quartz family, often noted for its pale to deep shades of purple. Amethyst has a hardness of 7, no cleavage, a white streak, and a glassy luster. The famous hue of this mineral is caused by trace amounts of iron that are trapped inside the quartz lattice.

This iron is then further modified through different levels of radiation deep within the earth, producing a wide range of colors from reds to deep purple.

Amethyst is often found as large crystals, or in clusters, or within geodes at many famous deposits in Brazil, Uruguay, Mexico, Russia, Canada, and South Africa. Here in the United States, Amethyst can be collected at the: Emerald Hollow Mine in Hiddenite, North Carolina Diamond Hill Mine near Abbeville, South Carolina Amethyst Queen Mine near Nancy Hanks Gulch, Colorado Amos Cunningham Farm near Due West, South Carolina. and Jackson’s Crossroads Amethyst Mine near Jackson Crossroads, Georgia.

Note: All of these locations require permission and most require a fee for collecting.
