What is Australian Opal?

Opal is an amazing natural gem made of silica minerals. Contrary to its crystalline relative’s quartz and agate, opal is not crystalline which means its structure is composed of amorphous silica. The main reason opal is unique is its capacity to emit bright colours from deep within the stone. When light strikes an opal, the tiny pieces of silica within the gemstone bounce around and reflect it to reveal a vibrant display of vibrant shades. This is one of the things that make opals so popular buying stone and also costly.

But you must wonder what makes Australia the most popular opal nursery? It all boils down to geochemical conditions in certain areas in Australia. These areas are home to rocks that support the development and production of sedimentary opal. Opal thrives in certain areas where, millions of years ago, geothermal springs flowed. Gradually, the minerals in the earth moved to the surface and then grew within the bedrock cavities, forming opal.

If you’re buying it for someone else, it’s essential to get an understanding of their tastes and preferences for this stone to ensure that they will love the item just as much as you do.

Types of Opal

Australia produces over 95 per cent of the world’s opals. Each one of the various types originates from different regions of Australia, and all appear distinct from the other.

Black opals from Lightning Ridge are the ‘Rolls Royce’ of opals. They are very rare and expensive. Boulder opals are sourced from Queensland Opal fields. They can be stunning in colour, however, they also have an ironstone backing, which increases their mass. However, it can make the opals stronger.

Crystal opals are transparent or translucent quality as well as those with good colour can fetch very premium prices. White opals originate out of South Australian opal mines and are characterized by a milky white body tone. This typically results in the colour becoming less vibrant. Nevertheless, a top-quality white opal remains stunning to look at.


To assess an opal’s value look at its colour play and body tone, brilliance, and pattern, as well as how thick the colour bar is and any imperfections like inclusions or cracks. 

Select an opal you like and that matches your skin tone. Red on black is the most desired and expensive, followed by yellow and orange green, but the most popular is blue. 

Check that the Stone Doesn’t have any cracks or flaws 

A reputable and honest opal seller will declare any faults or inclusions within the stone that can be seen by anyone with a keen eye. Natural faults and inclusions are acceptable but don’t purchase a stone that has cracks. If you’re looking at it in the flesh, ensure that it is dry before holding it up to a lamp to check for cracks. 

Be sure not to misinterpret the natural formation lines of the opal with cracks; eventually, you’ll be able to discern the distinction. A damaged stone is useless. The person from whom you purchase the stone is under an obligation to inform you about cracks or flaws in the stone before selling it to you.


The brilliance or brightness is a way in which the worth of opal is assessed. Three types of ratings are: Brilliant, Bright, and Subdued. Brilliant is the brightest and most expensive, while ‘bright’ is in the middle of the spectrum, and subdued has the lowest brightness. Opals with brilliant colours are stunning, but even subdued opals are pretty.


Always obtain a certificate authenticating the purchase. A certificate you get when you purchase an opal can be beneficial for insurance and resale value. It also holds an individual seller accountable.

Special care

Be aware that opals are extremely fragile and require special attention. Opals don’t respond well to sudden temperature fluctuations. Therefore, setting an opal into the jewellery piece requires the expertise of a professional. If you’ve picked an opal with a loose cut that you wish to set in jewellery, ensure that it is done by someone who is an expert in dealing with opals.

Don’t be put off by your choice.

We’re aware that too many choices can be overwhelming and often be left with nothing. Don’t be discouraged in this circumstance. But the more options you have, the greater chance it is that you’ll discover the perfect piece ideal for you or someone special to you. More options will also allow you to determine what’s an appropriate and fair price for the design and style you’re searching for. 

Choose the right seller

Selecting the right seller to buy opal jewellery could be a bit stressful if it’s your first chance of buying it. 

To avoid this, you should seek out advice from your family or friends before selecting the seller. It is also possible to inquire about the vendors and read their reviews as well as guidelines if you’re planning to select an online seller. 

Make sure to ask any questions that pop into your mind and then see the speed at which they answer your queries. Be aware that a trusted seller with excellent customer service will respond within hours, sometimes in minutes.
