In this article, we’re focusing specifically on the price of Australian Opal to help you know what to pay as a buyer. To properly address price points, we need to step back and take a broad look at Australian Opal.

What is Australian Opal?

Opals exist globally, however the largest supply of opals comes from Australia. In fact, Australian Opals make up a whopping 95% of the international supply of opal gemstones.

What makes Australia the prime nursery for opals? It boils down to the geological conditions of certain regions in Australia. These areas contain rock formations that foster the growth and production of sedimentary opal. Opal thrives in specific locations, where millions of years ago geothermal springs flowed. Slowly over time the minerals deep in the earth made their way to the surface and grew in bedrock cavities to form opal.

If you look at a map of Australia and pinpoint these locations, you’ll quickly realize that opal exists abundantly across the country. From the bush to the Outback, Australia is renowned for its natural and geological wonders. The most prominent locations of opal production exist in Australian Opal fields like Lightning Ridge, Queensland, South Australia, Mintabie and Yowah.

How Much is Australian Opal Worth?

To truly assess the value of Australian Opal is no easy task. That’s because each specimen has a multitude of factors that make it an entirely unique stone. For years, there was no hard and fast way to classify opals into a value system. To this day, prices of Australian Opal will invariably shift depending on the factors that affect the quality of the stone.

Factors That Dictate The Value of Australian Opal

Instead, we can look at the variables and features of each stone to get better acquainted with its value. There are precisely 10 factors that influence the price of opal: color, play of color, pattern, body tone, brightness, shape, inclusions (flaws), which opal field it came from, natural or treated and origin. While these variables relate to the physical properties of the stone, there is one outlying factor: supply and demand. When opal supply is low, the prices skyrocket. Conversely, high supply drops the price of Australian Opal.

Even with these factors in play, Australian Opal prices vary depending on where you buy it, how the miner evaluated it and what kind of opal it is. Let’s explore some of the ways Australian Opal is valued and priced.
