Opal, with its iridescent shimmer that reflects all the shades of the rainbow, is the gemstone of October. Known as the “stone of dreamers,” opal was associated with creativity, inspiration, and spiritual protection. This gem is often associated with magic and mystery. Considered the “foot of the rainbow” because it reflected all the colours of the rainbow. This phenomenon occurs when light is reflected and refracted through the silica microspheres inside the stone, creating a variety of colours and shades that appear to move and change when the opal is rotated under light. This unique chromatic effect makes opal one of the most fascinating and desired gemstones. The ancient Greeks believed that opal was a stone of great power and mystery. It was thought to have the power to predict the future and protect from negative influences. In some spiritual traditions, opal is also considered a symbol of transformation and rebirth. It is believed to help overcome times of crisis and difficulty, promoting personal and spiritual growth.
