   Gemstone of the Month : Citrine  

The gemstone Citrine is the official birthstone for the month of November. It is also the Planetary stone for the Sun Sign of Virgo and the accepted gem for the 13th and 17th wedding anniversary.

Citrine is a variety of quartz ranging in colors of yellow, yellow-brown, orange, dark orange-brown, reddish-brown.  Color: Pale yellow to a Madeira orange in all of its glorious golden and yellow colors. The yellow color is from the presence of iron, the darker the color - the higher the grade. Darker colors are more highly prized, including medium golden orange ("Rio Grande" citrine) and dark sherry-colored ("Madeira" citrine).   Also an earthy "Champaign" color is found.

Other yellow gemstones are often used for the November birthstone. The more expensive orangish-yellow topaz, reflective golden beryl and tough yellow sapphires, may be sold as citrine substitutes.

 


Description: SiO2 Citrine is transparent, coarse-grained variety of the silica mineral quartz . Citrine is a semiprecious gem that is valued for its yellow to brownish color and its resemblance to the rarer topaz.   Natural citrine is rare compared to amethyst or smoky quartz , both of which are often heated to turn their natural color into that of citrine.

The name's origin: The name citrine is derived from the French word citron meaning lemon.   Also called Citron, Goldtopas,  and Bohemian Topaz.

Birthstone: Citrine along with yellow topaz are birthstones of Scorpius (Scorpion): Oct. 24 - Nov. 21 .

Care and treatment: Citrine can be easily scratched. Natural (untreated, unheated) citrine may permanently change color if left in the sunlight for several hours, hence citrine jewelry should be kept away from prolonged exposure to strong light or heat.
