Whether you are an avid collector of natural stones, or you are just looking for something beautiful to wear, a fire opal from Australia is the perfect piece. This opal fire stone gemstone is known for its vibrant colors and translucent to nearly opaque quality. It can also be found in a wide range of shapes and sizes.
Unlike many of the other colors in the opal family, fire opal is rare. It has a transparent base with colors ranging from red to orange. It is usually cut into cabochons, but there are also finer stones available. These stones are coveted for their gaudy play of color.
Fire opal can be cut into cabochons, but its appearance can vary. Some stones have a flakey appearance, while others have a more rounded, faceted appearance. This can also affect the price of the stone. The price of the stone depends on its color, clarity, and overall appearance. The rarest fire opals can sell for up to $500 per carat.
Colors of fire opal can range from orange to red, and are often referred to as "dancing flames". The firey colors in opal are produced by tiny hydrated silica spheres. These spheres are about half a micron in diameter, which helps to diffract light into different colors of the spectrum.
Among the many precious opal varieties, the Australian Fire Opal is most well known for its extraordinary play-of-color. Its name comes from the Greek word opallios, which means to see a change in color. A play-of-color may appear as a pattern in a transparent opal, a flash of color when the stone is moved, or when the stone is exhibited in an incident light.
Fire opals are translucent to nearly opaque and can be cut into cabochons. The body color of opal may be orange, red, yellow, or brown. However, the most precious and valuable are the red and yellow stones.
Fire opals can also be found in Mexico and Central and South America. The name comes from the flash of color that the stone exhibits when the stone is moved. Some of the best opals are mined in Mexico.

Generally, Australian fire opals are rarely faceted. The standard chemical formula for Australian opals is SiO 2 H 2 O. This means that the opal has an average amount of opalescence. However, these stones do have defects.
In Australia, the majority of opal deposits are found in non-marine sedimentary rocks. This means that they were formed in a freshwater environment during the Cretaceous period.
During this time, the groundwater carried silica into the ground, which gradually hardened into a gel. The silica spheres were then arranged in a regular pattern. These spheres broke white light into colours. The smaller spheres provided blues and greens, while the larger spheres offered all colours. The colour and intensity of the play of colours were highly valued. The opalised shelly mollusks and fish bones found in Coober Pedy, SA, are valued for their appearance.
Several factors determine the cost of fire opal from Australia. The most important factors are color and play-of-color. However, there are also other factors, such as clarity, durability, and country of origin.
The color factor is divided into two categories: the background color and the play-of-color. The background color is simply the color of the opal, while the play-of-color is the arrangement of colors on the opal's surface.
The play-of-color can come in a variety of patterns. Some common patterns include pinfire opal, peacock opal, and mosaic opal. Some rare patterns include ribbon opal and windmill opal.
Another type of play-of-color is the radiated fire pattern. This is a pattern of parallel bands of color that resembles a rolling harlequin. These patterns are much less expensive than the common fire patterns.
