What You'll Learn
Black opals are the rarest variety of opals
The unique characteristics of black opals make them highly sought-after. Unlike ordinary opals, the dark body tone of black opals enhances the vibrancy of the rainbow or spectral colours present in the stone. This play of colour is often compared to fireworks against a dark night sky. The most valuable subtype of black opals is known as "black fire opal", which displays rare red colour flashes.
The value of a black opal is determined by several factors, including body tone, play-of-colour directionality, play-of-colour pattern, and brightness. Darker black opals, graded closer to N1 on the body tone scale, are considered more valuable. In terms of play-of-colour directionality, non-directional or "full-face" opals, which exhibit bright colours from all angles, are the most prized. Additionally, certain play-of-colour patterns, such as harlequin, Chinese writing, and ribbon, are rarer and more valuable. Finally, play-of-colour brightness graded B1 is the most desirable, with the value decreasing progressively from B2 to B7.
The rarity and exceptional beauty of black opals have made them a valuable commodity in the gemstone market. Natural Australian black opals can range in price from $50 to $5,000 per carat, depending on their quality. Top-quality black opals can even fetch prices of up to AUD $15,000 per carat, surpassing the value of some diamonds. The unique shapes, sizes, and patterns of black opals also make them ideal for custom jewellery, allowing individuals to create one-of-a-kind pieces that showcase the stunning play of colour that black opals offer.

They are found in Lightning Ridge, Australia
Black opals are indeed found in Australia, and the majority of them come from a single small place: Lightning Ridge, a town in north-western New South Wales. In fact, 97% of the world's sedimentary opals are sourced from Australia, with Lightning Ridge being the primary source for precious black opal gemstones.
Lightning Ridge is the largest and most famous source of high-quality Australian black opals. The opals from this region are so distinctive because of their unique composition of carbon and iron oxide trace elements, which give them their black body tone. This black body tone acts as a dark, contrasting background that makes the play of colours in the opal even more vibrant.
Black opals are also found in the US, Ethiopia, and Honduras, but the highest-quality black opals come from Australia. The quality of the opal is determined by factors such as origin, body tone, play of colour, predominant colour, and pattern. The brighter and more vibrant the black opal, the higher its value.
The black opals from Lightning Ridge, Australia, are sourced by various companies, including Black Opal Direct and Absolute Opals & Gems. These companies then craft the opals into unique jewellery pieces, such as rings, pendants, earrings, and bracelets. The opals are highly sought after, with some selling within days of being posted online.
The process of mining black opals in Lightning Ridge involves prospecting with a 9-inch auger drill. Once promising material is discovered, a 3-foot-diameter shaft is drilled to reach the opal-bearing level. When payable material is found, a mechanical digger is lowered down the shaft. This labour-intensive process reflects the value and rarity of the black opals found in Lightning Ridge, Australia.

Black opals are dark grey to black in colour
Black opals are mostly found in Lightning Ridge, Australia, which is the largest and most famous source of high-quality black opals. Ninety-seven per cent of the world's sedimentary opals come from Australia, and Lightning Ridge is the main source of precious black opal gemstones.
Black opals are also found in the US, Ethiopia, and Honduras, but the highest-quality black opals come from Australia. Australian black opals are characterised by their dark body tone, which can range from dark grey to jet black. The unique nature of carbon and iron oxide trace elements gives the opal its black body tone.
Black opals are the only type of opal found in nobbies or nodules. They are also the only type of opal with a black body tone and patches of colour. The black body tone of the opal is not related to the rainbow or spectral colours present in the stone. In fact, the rainbow colours in a black opal stand out much better than in lighter opals, due to the dark body tone.

They are the most valuable type of opal
Black opals are the most valuable type of opal. They are characterised by a dark body tone, ranging from dark grey to black. The darkness of the stone is caused by the presence of carbon and iron oxide trace elements. This dark body tone makes the rainbow colours in a black opal stand out more than in lighter opals, resulting in a vibrant play of colour. The highest quality black opals come from Australia, specifically Lightning Ridge in New South Wales. In fact, 97% of the world's sedimentary opals originate from Australia.
The value of a black opal increases with the darkness of its body tone. The most valuable black opals are those with a body tone closest to N1 on the body tone scale. The directionality of the play-of-colour also affects value, with non-directional or "full-face" opals being the most valuable. In addition, certain play-of-colour patterns, such as harlequin, Chinese writing, and ribbon, are rarer and more valuable. The brightness of the play-of-colour is another factor, with brighter opals being more valuable.
The unique shapes and sizes of black opals make them ideal for custom jewellery design. The wide variety of patterns and colours available means that finding the perfect opal can be a lengthy process. However, the right opal for a particular piece of jewellery can be a "love at first sight" experience. When purchasing a black opal, it is important to see it in person or, at the very least, view a video of the opal to truly appreciate its play of colour.
The price of a black opal can range from $50 to $5,000 per carat, depending on its quality. Top-quality black opals can even fetch prices of up to AUD $15,000 per carat. Black opals can be worth more than some diamonds, particularly traditional white diamonds. This makes black opals a valuable and sought-after gemstone for jewellery, including rings, pendants, earrings, and bracelets.

Black opals can be worth more than some diamonds
Black opals are indeed found predominantly in Australia, with 97% of the world's sedimentary opals originating in this country. The largest and most famous source of high-quality black opals is Lightning Ridge, New South Wales. Black opals are also found in the US, Ethiopia, and Honduras, but these are not of the same high quality as those from Australia.
Black opals are the rarest variety of opal and are distinguished by their dark body tone, which can range from dark grey to black. They are prized for their vibrant play of colour, which can include rare and sought-after patterns such as the Harlequin pattern. The value of black opals increases with darkness, with the most valuable stones being those closest to N1 on the body tone scale.
The value of any precious stone is determined by various factors, including rarity, quality, origin, market demand, and historical context. While diamonds are traditionally seen as a symbol of wealth and luxury, with extensive marketing campaigns cementing their status, black opals can be worth more than some diamonds, particularly traditional white diamonds. This is due to the rarity of high-quality black opals and the unique play of colour that they exhibit.
The price of a diamond varies depending on the Four Cs: cut, colour, clarity, and carat weight. A high-quality 1-carat diamond can range from $4,000 to $12,000 or more, while larger diamonds above 2 carats can reach prices well over $50,000 per carat. In comparison, top-grade black opals can command prices upwards of $10,000 per carat, with some exceptional stones exceeding this figure. Therefore, while top-quality opals are generally less costly than diamonds on a per-carat basis, there are many average or lower-quality diamonds that are less expensive than black opals.
Ultimately, the decision between investing in opal or diamond comes down to personal preference, as both have their unique characteristics and appeal.
