Black Opal is a variety of Common Opal that is usually opaque. This variety is most commonly found in mass form and is a very popular material to cut into palm stones, carvings, and jewelry.
Science & Origin
Some of the nicest pieces of Black Opal have been pulled out of Oregon although Australia has been known to have an abundance of this mineral. Black opals are rare gemstones with dark bodies, commonly black, bluish-gray, deep gray, or dark green. This gemstone makes gorgeous jewelry and is worn for astrological and healing purposes.
Australian black opal gemstones formed in rock formations throughout millions of years. Numerous black opals valued at hundreds of millions of dollars have been discovered in Lightning Ridge, which is well-known for this stunning and mysterious gem. Most black opal is mined in Lightning Ridge, New South Wales’s northern region. The most expensive and well-known variety of opals is the black Australian opal.
Early in the 1990s, opal was first discovered in Ethiopia. The stunning color play and distinctive waxy texture of Ethiopian opals make them incredibly beautiful.
Before we dive into the different types of black opals, let’s take a look at the stone’s composition. The chemical makeup and physical properties are identical to all other opal varieties. Opals are colorful jewels ranging from white to orange to black. The hues of black opal range from black to dark gray, but they are all distinguished by a dark body tone.

To understand a wide range of colors of black opal, you must first know what exactly is meant by ‘play of color.’ Basically, ‘play of color’ describes how light interacts in opals. The black opal allows light to enter, which then comes into contact with the layered silica spheres to reflect a dazzling display of colors.
A rainbow display known as “fire” or “play of color” is the outcome of this optical interaction. Black opal has other colors besides just black. It possesses a dark body tone that contrasts brightly with the light flashes. The best black opal is considered to have a wide range of neon hues that work together to produce a fantastic color play. As the gemstone develops a dark body tone from iron oxide and carbon traces, light can better reflect and emit a wide range of colors.
The dark body tone of the stone makes it simple to distinguish black opal from other gemstones. The patterns in synthetic black opal tend to look perfectly structured and artificial, compared to the natural flow of authentic opals.
Australian black opal is considered to be best for jewelry. These opals are earth-mined, natural, solid, and free of any invasive treatments that could alter their appearance or reduce their market value. At my shop, I take pride in offering only the finest quality gemstones, and when it comes to opals, I exclusively sell Ethiopian Welo opals.
One African locale is where you can find the brightly colored Ethiopian opals, often called Welo opals. Opals come from all over the world, but many opal mining locales produce distinct, beautiful opals unlike any other.

Definitely!While roughly 95% of the world’s opals come from Australian mines, modern Ethiopian opal discoveries have put this African mine close behind Australia in terms of opal production and quality. Many opal enthusiasts know Australia as the world’s opal capital, so are Ethiopian opals real?
Even more recently, an Ethiopian black opal played an essential role in the 2019 film Uncut Gems!
Types of Ethiopian Opal
All Ethiopian opals show play-of-color, but the body tone differs. The three key deposits produce distinct varieties, including:
- Precious Fire Opal: Abundant, translucent opals from the Wollo Province with the red, orange, or yellow body color of fire opals and play-of-color indicative of precious opal, often showing vibrant purple and green color flashes.
- Black Opal: Rare naturally black opals that are not hydrophane, found in the Stayish mine of the Wollo Province, though many Ethiopian opals are treated to be black.
- Shewa or Mezezo Opal: The first Ethiopian specimens discovered in 1994 in the Shewa province, typically reddish-brown, orange, or chocolate brown but often has problems with crazing-a type of damage where drying leads to web-like cracks.
- White Precious Opal: Ethiopian opals with white body color, bright color play, and much better stability than Shewa opals. These are typically found near Wegel Tena.
These examples don’t cover every type of Ethiopian opal, as the number of body colors and patterns rivals that of Australian opals. The key differences between Australian vs. Ethiopian opals are that Ethiopian opals are usually larger, rarer, and less expensive than Australian opals.
Ethiopian Opal Gemstone Properties
Unlike Australian opal that forms deep underground, Ethiopian opal forms high up in the mountains. Volcanic activity is behind these hydrophane opals’ formation, and they come out nobby-formed (like lump-shaped balls) rather than seam-formed like most opals.

Since the stone is new to the industry, Ethiopian opal grading is complex and somewhat subjective, but they’re generally graded on pattern, brightness, treatments, and color. Once mined, it’s time to cut and value these opals-but how are they graded?
Ethiopian opals are unique in their varied, vivid patterns, ranging from Welo Broad Flash to Fire Cloud! The most sought-after pattern is honeycomb, a pattern exclusive to Ethiopian opal where common opal forms a line with web-like inclusions across the stone. Stones with honeycomb patterns are typically cut as cabochons.
Brightness refers to a stone’s “fire,” or the colorful flashes caused by light dispersion. The fire within many Ethiopian opals shows a rare 3-dimensional effect. Color-wise, blue and green color flashes are typical, though the rare red flash may occur. In general, stones with brighter, more saturated fire command higher prices.
Besides basic filling treatments to reduce crazing, the three primary techniques are sugar-acid, smoking, and dyeing. A fair amount of Ethiopian opals have been treated.
A sugar-acid treatment involves soaking the opal in sugar-water, then sulphuric acid. The result is a collection of specks and stains on the surface that darken the body tone, thereby increasing the color play’s brightness. The smoke treatment produces similar results. This process requires wrapping the opal in paper, heating it in an enclosed container, then cooling and washing it.
Ethiopian opals’ hydrophane nature also lends well to dyeing, commonly seen on bright purple or pink Ethiopian opals, as these don’t occur naturally. Hydrophane opals take smoke treatments well, but this makes it harder to detect.
Ethiopian opals can be white, black, blue, red, pink, orange, or brown, depending on the mine. Colorless crystal opals come from the Wegel Tena mine. Body tone isn’t as crucial to Ethiopian opal value as it is for, say, black opals. The main significance of body color is its effect on the stone’s brightness and patterns.
Which color you’ll see in Ethiopian opals partly depends on the province it’s from, a fundamental part of the stone’s history!
Ethiopian Opal History
The modern discovery of Ethiopian opals only occurred over the last few decades. However, the oldest opals found in a Kenyan cave dating back to roughly 4000 BC were likely Ethiopian opals! Anthropologists believe man’s earliest ancestors used these opals to make tools.
The name “opal” comes from the ancient Sanskrit Upala, meaning “precious stone,” and later Greek Opallios meaning “to see a change in color.” Our prehistoric ancestors didn’t call them “opals,” though.
Fast forward to 1994: miners discovered the first Ethiopian opal deposit in the Shewa province. These precious opals were inside volcanic rock nodules and had brown, reddish-brown, or orange coloring. Unfortunately, they also were prone to crazing.
In 2008, miners discovered a second deposit in the Wollo province near Wegel Tena. Wegel Tena opals were more durable than Shewa opals and came in more attractive types like white, crystal, fire, and the occasional black opals. “Welo opal” soon became a trade name for this deposit’s opals.
Interestingly, Wegel Tena’s white opals have a high barium content, along with inclusions of pyrite and carbon at times. Some specimens also have “digit” patterns, where layers of common and precious opal make the color play appear in finger-like columns.
The last major discovery in 2013 occurred at the Stayish mine, also in the Wollo province. Some specimens produced were white or crystal opal, but the majority were black or dark gray opal.
Today, the Wegel Tena deposit is known for stunning white and crystal opal, while the Stayish mine is known for its black opal. Ethiopian opal’s play-of-color is generally stronger than that of Australian opal, and the horizontal tunnels make for easier mining than vertical shafts. Ethiopian miners have already produced more than 1,500kg (3,300lbs) of rough Ethiopian opal!
