Description - Birthstones or sometimes known as Zodiac Stones are 12 different gems which have been assigned to the months of the year or Zodiac signs. Unfortunately there are differences in the lists given in different publications and around the world as to which stone corresponds with each month/zodiac sign. Fortunately for us though that means more answers in this Can You Name? We have 4 different lists including, Modern, Mystical, Traditional and Ayurvedic birthstone and we want you to name all of them. Some even have multiple stones for each month. Good luck.
