Birthstones, Zodiac and Anniversary Stones

Birthstones are of special interest to gemstone lovers and the association of specific gemstones with months of the year goes back centuries. As the famous gemologist G.F. Kunz noted in his book, The Curious Lore of Precious Stones, "There is no doubt that the owner of a ring or ornament set with a birthstone is impressed with the idea of possessing something more intimately associated with his or her personality than any other stone, however beautiful or costly. The idea that birthstones possess a certain indefinable, but nonetheless real significance, has long been present and still holds a spell over the minds of all who are gifted with a touch of imagination and romance."

Precious gems were first associated with signs of the zodiac, and were adored for their special gemstone meanings. The modern birthstone list was formulated by an organization known as JA (Jewelers of America) in 1912. Birthstones are especially popular for use in gemstone jewelry, such as birthstone rings and birthstone pendants, and are sought-after for religious jewelry, particular in reference to the gems of Aaron's breastplate and Islamic gemstones.
