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 alexandrite was named after Czar Alexander II and is one of the most desired gems. Its color changes with the lighting surrounding the stone, which is called its phenomena.
Carnelian has been designated as modern birthstone for July in Britain alongside ruby. Carnelian was also the July birthstone in the old Arabic calendar. Before the gemstone appeared in these calendars as the stone for July, carnelian was a zodiac stone for Leo, which falls partly on the month of July. This birthstone of July is the red variety of chalcedony. The July gemstone is believed to fuel passion and desire. See also Carnelian: Stone of Passion.
