Opal is a gemstone made of tiny silica spheres and water, famous for its flashing rainbow "play of colour". It is the October birthstone and traditionally kept for creativity, joy, love and emotional expression. In Indian astrology it is often worn as an upratna, or substitute, for diamond, for Venus (Shukra). Opal is delicate: keep it away from heat, sudden temperature changes, knocks and soaking.

Let's start simple
What is opal?
Opal is silica with water trapped inside, typically between 3 and 10 percent. In precious opal, tiny silica spheres are stacked in neat rows, and they split light into rainbow flashes that change as you move the stone. Australia produces most of the world's precious opal, and Ethiopia is now a major source too.
Its ever-changing colours made it a symbol of creativity, emotion and imagination.
"Every opal holds its own small rainbow, and no two are the same."
