  • What is special about opals?

    Opals are a truly unique gemstone. They are renowned for the radiant patterns of colour within the stone; in fact, the way opals reflect light into rainbows of colour is so unique, it has its own name – opalescence.

    Opals form in a range of colours, with their main colour ranging from white to black, and bright red to blue, with different types featuring a unique kaleidoscope of colours within.

    Opals symbolise hope, happiness, and love, making them a beautiful gesture for your loved ones with October birthdays.


  • How are opals formed?

    Most of the world’s natural opals come from Australia. Opals are formed when water mixes with silica in rock underground. Over time – over millions of years, in fact – and where the conditions are right, an opal forms.
