Factors to consider before purchasing opals

Opals are beautiful and unique gemstones that have captivated people for centuries. Opals have a long history of association with Australia and are highly prevalent in that country’s culture. Australian opal is a significant component of the Australian economy, with an estimated 95% of the world’s supply coming from that country.

Over 8,000 people are employed in the region by the industry, which has an estimated value of 2.6 billion AUD. Every year, Australia produces roughly 3,000 tonnes of opal, most of which is transported abroad. If you are considering purchasing an opal, several essential factors must be considered to ensure you get the best value for your money.

Origin: One of the first things to consider when buying an opal is where it comes from. Opals can be found in several countries, but the most prized opals come from Australia. Australian opals are known for their bright, vibrant colours and unique patterns, making them highly sought after by collectors and jewellery lovers.

Colour and clarity: The colour and clarity of opal are two of the most important factors to consider when making a purchase. Opals can range in colour from white to black, with a wide range of hues in between. The most valuable opals have a bright, vivid colour and a clear, transparent appearance. If an opal is cloudy or dull, lacking in colour, it will be less valuable and desirable than a fine, bright opal.

Carat weight: The opal weight is measured in carats, with one carat weighing approximately 0.2 grams. An opal’s carat weight is one factor that can impact its value, with larger opals generally being more valuable than smaller ones. However, it’s essential to remember that opal size does not necessarily determine its quality. A small, high-quality opal can be just as valuable as a large, lower-quality one.

Shape and cut: The form and cut of opal can also impact its value. Round, oval, and pear-shaped opals are among the most popular cuts, while freeform and cabochon cuts are less common. The opal cut can affect how much light it reflects and how well the colour and patterns are displayed, so it’s essential to choose a cut that highlights the unique features of the stone.

Type of opal: There are several different opals, including white opals, black opals, boulder opals, and fire opals. Each opal type has unique characteristics and qualities, so it’s important to know what you’re looking for before making a purchase. White opals are the most common type and are known for their delicate, pastel colours, while black opals are the rarest and most prized, with their deep, rich colours and intricate patterns.

Treatment: Some opals may have been treated to enhance their appearance or to improve their durability. For example, some opals may have been dyed to change their colour or treated with a hardening solution to make them less brittle. It’s essential to be aware of any treatments an opal has undergone, as this can impact its value and quality.

Price: Finally, it’s essential to consider the cost of an opal before making a purchase. An Australian opal can range in price from a few dollars to several thousand, depending on its quality, size, and origin. It’s essential to set a budget for your opal purchase and shop for the best value. Remember that the cheapest opal may only sometimes be the best choice, as it may have lower quality or be treated in some way.

In conclusion

Buying an opal is a personal and exciting decision, and by taking the time to consider the factors discussed above, you can ensure that you make the best choice for your needs and budget. Whether looking for a beautiful piece of jewellery or a unique collectible, opal is a stunning and timeless choice.
