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.
