Birthstone
I bet you all know about your zodiac signs right? What about your birthstone?
From Wikipedia: A birthstone is a gift of a precious material (jewelry, mainly gemstones; themselves traditionally associated with various qualities) that symbolizes the month of birth in the Gregorian Calendar. It is sometimes also called birthday stone (cf. infra; but that word is, confusingly, sometimes used as a synonym for an anniversary gift, which is related to the recipient’s age, that is, year of birth).

Mine is diamond! I wonder when will it come to me 🙁
