October Birthstone - Tourmaline and Opal;
Tourmaline is the birthstone for October according to the modern list, however Opal is the gemstone on the ancient list for October so both can apply. Opals are in a class by themselves. As a species, Opal is so unique it has its own descriptive vocabulary. More than any other gem, each Opal is distinctly individual. Opals are the most delicate gemstones that are commonly worn and require special care. Tourmaline is one of our most popular gems. No other mineral comes in more colours and some of the combinations are in a class by themselves.
