However, there has been some indecision in regards to June’s and July’s Birthstones. Originally it was thought that your birthstone corresponded to your Zodiac Sign. In later years that changed to the Roman calendar months and the birthstone was associated with the month the sign dominated, not the sign itself. Traditionally Pearl has been July’s Birthstone as it corresponds to Cancer the Crab, as the Zodiac sign is dominate in July. Recently the list has been changed with no date of record, to include Ruby. The lists have omitted Agate and Carnelian for June and replaced them with Pearl. (The Zodiac sign of Cancer begins at the end of June)
It is believed that the birthstones originated from the Bible and are taken from the Breastplate of Aaron, Exodus 28: 15-21; they represent the twelve tribes of Israel. Set in four rows they correspond to the Zodiac at that time. In order they are listed as:
The First Row: Sardius, Topaz, Carbuncle (or Emerald)
The Second Row: Emerald (or Carbuncle), Sapphire, and Diamond
The Third Row: Jacinth, Agate, and Amethyst
The Fourth Row: Beryl, Onyx, and Jasper
The stones may also be taken from the foundations for the walls of the new Jerusalem, and may be found in the book of Revelations 21: 19 -21. Listed in order of the Roman calendar and the layers: Jasper, Sapphire, Chalcedony, Emerald, Sardonyx, Sardius, Chrysolite, Beryl, Topaz, Chrysoprase, Jacinth, and Amethyst.
