The Ruby is associated with the month of July in the tradition of birthstones, in relation to the color red, historically linked to the summer period and the most intense hues of the year.
It belongs to the corundum family and is defined exclusively by its red coloration, while all other color varieties of the same family are classified as sapphires.
Ruby hues can range from lighter red to more saturated and deep colors. The distribution of color is one of the elements observed in the visual distinction between different stones.
