As an aspect of horoscopes based on astrology, birthstones have a pretty fascinating story, going back at least to the Middle Ages when people wore them for good luck, for prophetic powers, and even for spell casting.
They might even go back to biblical times when something akin to birthstones was discussed by 1st-century historian, Josephus. However, it wasn’t until the 18th century that birthstones were assigned months. Later, in 1912, the National Association of Jewelers defined the list of birthstones we know today.
But more than their storied history, people love birthstones because they’re fun to wear as well as are associated with good luck and good health.
