The month of May! Flowers, blue skies, warm weather ... there's no going back to the darkness and cold at this point! Traditionally, this month is represented by the vibrant, precious emerald - a stone representing life and rebirth. The emerald is also seen as a gem that promotes good health and positivity. The modern birthstone for May is chrysoprase - a milky green stone believed to help clarify problems while also strengthening the workings of insight.
