Our Unique Australian Fire Opal

Australian fire opals are precious opals from the opal capital of the world, Australia. As precious opals, these gems display the fiery play-of-color that gives them their namesake.

Technically, there are two definitions of fire opal: 1) the translucent to transparent red, orange, yellow, or brown opals best known from Mexico, or 2) the precious opals with various body colors but especially strong play-of-color, most desired with fiery red to orange color-play. 

While Mexican fire opals can be precious or common, Australian fire opals are always precious — the price of these fire opals often depends on the strength of their color-play.

The symbolism of Australian fire opals is rooted in joy, passion, clarity, balance, hope, and inspiration. Indigenous Australians have folklore about the natural fire opal’s colors originating from the creator deity coming to Earth on a rainbow. 

FAQs

How does fire opal compare to other types of opals?

What factors affect the value of an Australian fire opal?

How can I identify a genuine Australian fire opal?

A major sign that a “natural” fire opal is actually synthetic or simulated include patterns that are too perfect (often with a vertical columnar pattern from the side). A very glassy top and/or a visible seam at the bottom is a sign of an assembled doublet or triplet opal.

What should I look for in an Australian fire opal gemstone certificate?

A fire opal gemstone certificate should come from a reputable, third-party lab of expert gemologists. Your natural fire opal’s certificate should ideally have a unique reference number that’s searchable on the lab’s website.

Some Australian fire opals are treated with dye or smoking (often to simulate precious black opal) or Opticon oiling (to hide blemishes or instabilities like crazing). Here at Opal Auctions, we pride ourselves on offering all natural fire opal and keeping sellers accountable for specifying any gemstone treatments through our Opal Sheriff Program. 

What is the best cut for an Australian fire opal?

Can Australian fire opal be used for engagement rings and other special jewelry pieces?

Yes, they can! Australian fire opals are a popular alternative to diamonds for engagement rings and other sentimental jewelry, and they’re often set with other gemstones that compliment the array of colors in the opal. Just be sure to choose an opal ring with proper settings, as opals aren’t as scratch-resistant as other stones, and know how to properly take care of your natural fire opal engagement ring. 

Are there any special care instructions for Australian fire opal jewelry?

Yes, natural fire opal jewelry (and all other opal accessories) require proper care to maintain their durability and shine. Avoid mechanical systems like steam or ultrasonic cleaners; instead, use a soft cloth and warm, soapy water to wipe down your natural fire opal.
