About Birthstone Jewelry

May Birthstone: Emerald
May's birthstone, with its vibrant, bottomless green, is a powerful symbol of renewal, fertility, and joy. Those born in May carry the emerald to attract success, personal growth, and inner peace. Some say this captivating stone even helps predict the future.
History of Birthstones
Chances are you can name your birthstone, but have you ever wondered how certain stones came to be associated with particular months? Most gem scholars trace the tradition to the Old Testament story of Aaron, whose breastplate was decorated with twelve precious stones, one for each of the twelve tribes of Israel. Over time, these stones were linked with certain powers and tied to particular astrological signs, and later to calendar months.
There are many variations of birthstone lists, including Mystical birthstones, which originate from Tibet and date back over a thousand years, and Ayurvedic birthstones, associated with ancient Indian medicine and beliefs. Birthstones have also been tied to ancient Pagan religions, and even to the collective wisdom of the legendary lost city of Atlantis.
The Modern birthstone list, perhaps the most universally known, was released by the American National Association of Jewelers and officially adopted in 1912. Whether you embrace birthstone lore, or look upon it with a skeptical eye, there is an undeniable appeal to collecting a beautiful gemstone that is reputed to hold special power, meaning, and good fortune just for you.
