FAQs About Opal Jewellery

What Are the Different Types of Opals?

Opals come in a variety of types, each with its own distinctive characteristics. Here’s a breakdown of the most common types:

  • Black Opal: This is the most valuable and rarest type of opal, found primarily in Lightning Ridge, New South Wales. Black opals have a dark body tone that enhances their vivid play of colours, creating stunning contrasts of blue, green, red, and other hues.
  • White Opal: Also known as “milky opal,” white opal has a light or white body colour. It is typically found in South Australia, especially around Coober Pedy. While it may not be as vivid as black opal, its soft and ethereal colour play makes it highly sought after.
  • Boulder Opal: Unique to Queensland, boulder opals are characterised by the presence of ironstone in the matrix. This type of opal can display striking patterns as the opal forms within the cracks and crevices of the host rock. Its rich, earthy undertones create a beautiful contrast to the vibrant colours within the stone.
  • Crystal Opal: Crystal opals have a transparent to semi-transparent body tone, allowing light to pass through and intensify the gemstone’s colour play. They can be found in various Australian locations and are highly prized for their clarity and brightness.
  • Fire Opal: Unlike other opals, fire opals do not always display a play of colour. They have a warm body colour ranging from yellow to red, reminiscent of fire. Most fire opals come from Mexico, but they have become a popular choice in modern jewellery designs.

Each type of opal offers a unique allure, making it easy to find a piece that matches your style and preference.

Why Is Australia Famous for Opal Jewellery?

Australia is home to about 95% of the world’s opal supply, making it a global leader in opal production. The country’s unique geological conditions, with ancient sedimentary basins, provide the perfect environment for opal formation. The most famous opal mining areas include:

  • Lightning Ridge (New South Wales): Known for producing the world’s finest black opals.
  • Coober Pedy (South Australia): Often referred to as the “Opal Capital of the World,” it produces white and crystal opals.
  • Andamooka (South Australia): Renowned for its beautiful matrix and crystal opals.
  • Queensland: Known for its boulder opals, which are prized for their durability and striking natural patterns.

Australia’s opals are renowned for their quality and vibrant play of colour, making them a top choice for jewellery. Australian opals are not just gemstones—they are a piece of the country’s rich heritage and history, making them a meaningful gift or keepsake.

How Is Opal Formed?

Opal formation is a fascinating process that takes millions of years. Unlike crystalline gemstones, opal is an amorphous form of silica. It forms when water carrying silica seeps into cracks and cavities in rocks. Over time, as the water evaporates, tiny silica spheres are left behind, stacking in a way that creates the play of colour characteristic of opal.

The colours seen in opals come from the diffraction of light through these silica spheres. The size and arrangement of these spheres determine the colour patterns and intensity, with larger spheres producing reds (the rarest) and smaller ones creating blues and greens. This complex formation process makes every opal unique, with no two stones ever being exactly alike

What Should I Look for When Buying Opal Jewellery?

When purchasing opal jewellery, consider the following factors to ensure you get a piece of good quality:

  • Play of Colour: The play of colour is the hallmark of a high-quality opal. Look for vibrant, lively colours that are evenly distributed across the stone. An opal with a strong red or multicolour display tends to be more valuable.
  • Body Tone: The body tone of an opal can range from dark (black opal) to light (white opal). Darker body tones tend to enhance the brightness of the colours, making black opals particularly valuable.
  • Pattern: The patterns within an opal can significantly affect its value. Common patterns include harlequin (checkerboard), pinfire (small dots of colour), and broadflash (large flashes of colour). Each pattern has its unique appeal, with harlequin being one of the rarest and most sought-after.
  • Clarity: Crystal opals should be relatively clear, while other types may have some inclusions. However, the clarity should not detract from the beauty of the play of colour.
  • Cut: Opals are typically cut into cabochons (domed shapes) to best display their colour. A well-cut opal will have a smooth, symmetrical shape, allowing the colours to shine from all angles.

By considering these factors, you can find a piece of opal jewellery that matches your style while offering the best value.

How Do I Care for My Opal Jewellery?

Opals require special care to keep them looking their best due to their delicate nature. They have a relatively low hardness (5.5-6.5 on the Mohs scale), making them more susceptible to scratches and damage. Here are some tips for maintaining your opal jewellery:

  • Avoid Extreme Temperatures: Opals contain a small percentage of water, making them sensitive to sudden temperature changes. Extreme heat or cold can cause the opal to crack, a phenomenon known as “crazing.”
  • Keep Them Away from Chemicals: Opals should be kept away from harsh chemicals, including household cleaners, perfumes, and even chlorinated water. These can damage the surface and dull the stone’s brilliance.
  • Store Carefully: Store your opal jewellery separately from harder stones like diamonds or sapphires to prevent scratching. A soft pouch or lined jewellery box is ideal.
  • Clean Gently: Clean opal jewellery using a soft, damp cloth. Avoid using ultrasonic cleaners or steam, as they can damage the opal.

With proper care, your opal jewellery can remain as beautiful as the day you bought it, allowing you to enjoy its captivating colours for years to come.

Why Is Opal Considered a Lucky Stone?

Opals have long been associated with luck and mystery. Ancient cultures believed that opals contained the power of all gemstones due to their rainbow-like colours. In Roman times, opal was considered a symbol of hope and purity, and it was believed to bring good fortune to those who wore it.

In more recent history, opals have also been associated with creativity and inspiration. They are said to stimulate originality and amplify positive emotions. As a result, opal jewellery is often given as a gift to celebrate milestones, such as weddings, anniversaries, and birthdays (especially for those born in October, as opal is the birthstone for this month).

Despite a few myths about opals being unlucky, which surfaced in the 19th century, most people today regard them as beautiful symbols of individuality and good fortune. Wearing an opal can be a personal statement, reflecting the unique play of colour within each stone, much like the personality of the wearer.

Opal jewellery, with its vivid colours and rich heritage, remains a timeless choice for those who appreciate nature’s artistry. Whether you are drawn to the dramatic flashes of black opal or the gentle glow of a white opal, this gemstone offers a piece of Australian magic that you can carry with you wherever you go.
