The Christian Intellectuals in the 5th century found a link between the twelve gems in the Breastplate of Aaron, twelve months of the year, and twelve signs of the zodiac. According to them, every gem has a connection to a specific month or astrological alignment, and they would get therapeutic advantages for wearing one at that time. So, to get full benefits, people started wearing one gem every month of the year and gave distinct meaning and value to them. Birthstones and zodiac signs offer meaningful personalization to ornament design. At present, the fame of birthstone jewelry is just not limited to any region, age, or gender.
