Quartz Varieties

Quartz mineral specimens can be found in a wide variety of colors. The varieties are numerous, and you’ll find many of these Quartz mineral specimens for sale below and on adjacent pages, including these following varieties and colors:
Rock Crystal Quartz: The name for clear, colorless Quartz-void of any inclusions or impurities.
Milky Quartz: White coloring due to microscopic inclusions of gas and/or liquid during crystal formation.
Smoky Quartz: Light-brown to dark brown coloring due to natural irradiation. It’s very common to see clear Quartz that has been artificially irradiated – there’s nothing wrong with the practice unless it’s being deceptively sold as natural.
Rose Quartz: A pink color, usually forming in large masses, and in much rarer cases, in crystallized form. The cause of the pink color is debatable – is it iron or manganese or microscopic fibers of Dumortierite? I wouldn’t lose any sleep over it . . .
Citrine: Pale to dark yellow colors, naturally occurring Citrine Quartz is rare. The natural yellow color is caused by iron oxide impurities. Most Citrine on the market is heat-treated Amethyst.
Ametrine: This is a combination of Amethyst and Citrine, alternating colors of purple and yellow.
Red Quartz: Also called Tangerine Quartz and Ferruginous Quartz, this reddish coloring is due to coatings and/or inclusions of red Hematite.
(I discuss and offer Amethyst [purple] Quartz under its own category Quartz/Amethyst, due to its immense popularity and world-wide availability.)
