Sold Without ReserveFluoriteDe'an Fluorite Mine, Wushan, De'an County Jiujiang Prefecture, Jiangxi Province, China Overall size 12.0 x 9.0 x 6.5 cm. From the important De'an locale, featuring a rich overgrowth of the highly translucent vivid purple 'grape jelly' fluorite well known from this deposit over white drusy matrix with scattered minor colorless cubic fluorite. With custom lucite base. Certainly one of the most popular collectible minerals, calcium fluoride (CaF2) occurs in numerous important deposits spanning the globe. The nearly infinite array of available colors, often occurring in multi-color zoned “phantom” growth, have long delighted mineral collectors and lapidaries alike. Valuable as a smelting agent and for use in certain types of glass and optics, it has been mined in great quantities for industrial purposes. Vividly colored specimens with aesthetic crystal growth are best known from classic North American deposits in Illinois and Tennessee, European localities in Spain and England, and more recently from several exciting Chinese discoveries. While Silicon Oxide (SiO2) or quartz may be the second most common mineral present in the Earth’s crust, many rare and unusual varieties offer opportunities for collectors. From the royal purple and golden hues of amethyst and citrine, to the intense turquoise and apple green of chrysocolla and chrysoprase, quartz has an incredible spectrum of available colors. Rare and unusual crystal forms such as scepters, gwindels, faden, elestial and “spirit” quartzes create incredibly diverse aesthetics to enjoy. As a prime component within many of the great crystalline environments, quartz is also a frequent partner to and basis for other mineral growth. Classic combinations like smoky quartz and amazonite, fluorite on quartz, and spessartine garnet on smoky quartz offer fantastic contrasts of color and form.
