Different cultures have different birthstone lists. Gems4friends.com provides lists of modern, traditional (dating back to the 15th century,) mystical (ancient Tibetan,) and Ayurvedic (Indian medicinal) birthstones. There is also a list of stones associated with each zodiac sign. Traditional birthstones are often the same color as their modern counterparts. This is due to the fact that people could tell the difference between stones of different color long before they understood the mineral composition and rarity of different stones.
Birthstone jewelry is an excellent birthday present, though some birthstones, particularly rubies, diamonds, emeralds, and sapphires, are more expensive than others due to their rarity. A large selection of birthstone jewelry can be found at jewelrycentral.com.
