Opals are October's birthstone due to their shifting iridescent colours. In addition to being known as the stone of hope, innocence, and purity, opal inspires creativity and imagination. Opals were also thought to bring good luck to the ancient Romans. Opal is composed of hundreds of millions of tiny silica spheres of different sizes that play a unique role in its colour play. By diffracting light through these spheres, different colours of the rainbow can be seen. Discover our October Birthstone Jewellery collection.
In the ancient Greek language, the Greek word opal meant 'to see a change of colour'. As early as the Middle Ages, the Romans often looked at opals with awe, thinking they were the most magical gemstones because of their rainbow-like iridescent properties as well as the fact that they have colours that none of the other gems possesses.
