It is thought that the assignment of a particular gemstone to a given month originally came from the qualities that symbolized that month in the Gregorian Calendar. The breastplate of Aaron in the Bible, containing the twelve stones representing the twelve tribes of Israel may be the origin of the idea of birthstones.
If you had do some researching and looking around, you will realize that birthstone lists may vary from one source to another. In 1912, the American National Association of Jewelers adopted the list below and it is currently used in the United States and many other countries.
June Pearl, Moonstone or Alexandrite
September Peridot, Sardonyx or Sapphire
October Tourmaline or Opal
November Yellow Topaz or Citrine
December Zircon, Turquoise, Lapis Lazuli, Blue Topaz or Tanzanite

Gemstone Spotlight: Citrine
Citrine is the BIRTH STONE for November.
Citrine is a quartz crystal and its colors range from yellow to orange. Yellow Citrine is somewhat rare in nature, but by heating Quartz stones such as Amethyst, the colors can be changed to golden yellow to orange. Citrine that has been heat treated tends to have more of the red tones resulting in attractive golden colors.
The heat treatment process usually produces a permanent color change. In nature, the heat of volcanos can convert different varieties of quartz to the yellow and golden hues. Citrine has a more denser richer color than CZ which is colored yellow.
Citrine has a hardness rating of 7 on a scale of 1 to 10. A diamond is the only stone with a hardness rating of 10. For practical purposes a 7 is a “good” level of hardness for sterling silver rings and jewelry. Most natural colored stones have a hardness rating of about 7 to 8.
Unfortunately some gem merchants have sold citrine claiming it to be the more expensive orange-yellow topaz. Topaz is in a different family of stones and is not related to quartz.
Citrine in ancient times was believed to aid in bridging the gap between mental, emotional, and intuitive levels of being. Citrine is said to bring happiness, cheerfulness and hope. I hope that the purchase of a Citrine Sterling Silver Rings would bring you happiness.
