There are two birthstones for the month of June. Alexandrite was the traditional birthstone for June, but due to its scarcity and cost, pearl has become June's common birthstone.

The choices of modern birthstones for July in Britain are indicative of the July stone color. The most popular modern, traditional, as well as ancient birthstone of July, ruby, is red in color. Carnelian, the alternate birthstone for July in Britain and the July gemstone in the ancient Arabic calendar, is also red.
