Customized October Birthstone Jewelry: Grandeur of Opal
If you are thinking about what is the official October birthstone, then you would be happy to know that there are two semi-precious gemstones designated as October birthstones: tourmaline and opal. The first birthstone list, which was created in the 1st to 5th century AD, and inspired by Biblical gemstone lists, had beryl and aquamarine as October’s birthstone. The first standardized list came from the Jewelers of America (who were known as the National Association of Jewelers at that time) in 1912, where opal was designated as the primary birthstone of October, and tourmaline was mentioned as its alternative.
