Boulder opal occurs in sedimentary rock deposits, often from the Cretaceous age; these deposits formed 100 million year ago. The rock itself is often a brown sedimentary matrix rock that has iron content. These iron layers form the host rock that the opal forms into. The opal is the layer of colorful or milky looking blue, green, red and purple that form inside the “boulder” host rock. Fire opal is opal that has a fiery flash of color, often with reds, greens, blues, and oranges. It is formed similar to boulder opal, but is often cut with less of the sedimentary matrix rock. The beauty of boulder opal is the mix of matrix sedimentary rock and opal that together make a unique gem creation.

Opal has many stories associated with it throughout history. Opal takes its name from the Latin word Upala meaning precious stone. The Romans believed opal was the symbol of hope and purity. They called it cupid paederos (child as beautiful as love) and thought the wearer of opal would be safe from disease. The Arabs believed that opals fell from heaven in flashes of lightning. Ancient Greeks believed that opal had the power of giving foresight and the light of prophecy to their owners. Cleopatra is said to have worn an opal to attract the attention of Mark Anthony.

Some believe opal to be a stone useful to create good humour and a good mood; it is useful in creating joy. It may be used to stimulate the lymph, kidneys, and intestines.
