What month does the ruby stone represent?

The ruby is traditionally associated with the month of July. It is one of the birthstones for that month, along with the onyx. Birthstones are gemstones that are associated with each month of the year, and are often given as gifts to people born in those months. The concept of birthstones dates back thousands of years, and different cultures have assigned different stones to different months. However, the modern list of birthstones used in the United States was standardized by the Jewelers of America in 1912.
