The traditional October birthstone for our October babies is none other than Opal. It is a unique gem with a diverse range of colors and optical effects. 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. Holistic healers tend to use opals to connect with cosmic consciousness and intensifying emotions. It is also said that wearing opal jewelry enhances the intelligence and creativity of the wearer, heightening his connection with the self. Some people even say that wearing opal jewelry strengthens memory and recalling power.
