Australian Opals: The Most Sought-After and Valuable Gemstones

When talking about the finest and most desirable types of opal, Australian opals come on top of the list. It is no wonder that Australia accounts for 95 percent of the world’s opal mining industry. With so many opals being extracted from different mines in Australia, it is no surprise that these precious gemstones dominate the global market. The value of an Australian opal is determined by various factors such as its natural state, brightness, clarity, country of origin, color, pattern, and play of color.

Characteristics of Australian Opals

Unlike any other gemstone, Australian opals are not a homogeneous group. Each piece has distinct variations that make it unique. While there are smaller deposits of opals in other countries, Australian opals are recognized as the best. Australia’s opal fields are situated in New South Wales, Queensland, and South Australia. Lightning Ridge in New South Wales is famous for black opals, while Boulder opals are found in Queensland. Milky or white opals, on the other hand, can be mined in South Australia.

The most valuable type of Australian opal is the black opal that comes from New South Wales. Additionally, the White Cliffs area in this location is home to rare opal pineapples, which are fossilized pieces of opal. Boulder opals are unique to Queensland and have unusual patterns due to their formation process. Crystal opals consist of a translucent to semi-transparent background. Meanwhile, water opals resemble crystal opals but feature a faint play of color. Play of color patterns vary, including pinpoint with little patches of color, mosaic or harlequin with broader patches of color, flame with reddish streaks, and peacock with mostly green and blue hues.

Why Australian Opals are Special

Opals are one of the oldest gemstones globally, with records dating back to 4000 BC. In Rome, people referred to them as opalus, a Latin word meaning precious stone. Precious opals are classified based on their vibrant color display, which gives them the name of fire opals. The multi-dimensional bright color display is unique to these valuable gemstones. Opals come in different colors such as blue, green, orange, purple, red, yellow, or black, depending primarily on the background color, which is due to impurities present in the silica.
