13.2 Birthstones and the Zodiac


13.2: Birthstones and the Zodiac

You can obtain lists of birthstones from jewelry stores or from books on gems and jewelry. The lists often vary (by one count, there are nearly 50 different lists!) but the following table shows commonly accepted birthstones, along with some backups:


Month Modern or Traditional Birthstones Mystical Birthstones
January Garnet (or Tanzanite or Rose Quartz) Emerald
February Amethyst (or Tourmaline or Onyx) Bloodstone
March Aquamarine (or Bloodstone) Jade
April Diamond (or Nephrite Jade or Quartz) Opal
May Emerald (or Agate or Chrysoprase) Sapphire
June Pearl (or Alexandrite or Moonstone) Moonstone
July Ruby (or Onyx or Carnelian) Ruby
August Peridot (or Sardonyx) Diamond
September Sapphire (or Malachite or Lapis) Agate
October Opal (or Tourmaline) Jasper
November Topaz (or Citrine or  Rubellite) Pearl
December Turquoise (or Blue Topaz, Zircon, Lapis Lazuli, Tanzanite, or Coral) Onyx


When it comes to Zodiac Stones, lists vary tremendously. In fact, for each sign of the Zodiac, some ascribe a whole range of stones: a birthstone, a zodiac stone, a talisman stone, a mystical stone, a planet stone—even a lucky charm stone! This only adds to the confusion when it comes to ascertaining just what is supposed to be one‘s birth stone. While I‘ve seen lists of all sorts, the following is what I‘ve settled on. Be aware, though, that kids in your club may very well come up with different lists.
