Birthstones are a fascinating intersection of gemology, culture, and history. Each of the twelve months of the year is associated with one or more gemstones, believed to bring protection, good fortune, and personal meaning to those born under their time. These gemstones have been cherished for centuries, with roots in ancient traditions and evolving through modern interpretations. This guide explores the birthstones for each month, their gemological properties, historical significance, and the myths and beliefs that surround them.
