Early civilizations in both India and Babylon as far back as 3000 BC attributed rare and beautiful gemstones with magical properties. The early gem buyers sought advice from astrologers first, in hopes that they could influence the forces that were identified with the planets in their favor. There was no formal classification of gemstones, a gem was assigned each sign of the zodiac based on a color system. Color was thought to unleash the power attributed to the stone.The Indian and Babylonian systems both linked the ruling planets with their corresponding gems. Giving rise to the zodiac type system that we use today.
