Black Opal from Ethiopia: A gem of dark power

Among the wealth of gemstones, the black opal from Ethiopia stands out like a mysterious star in the night sky. Its dusky color, hiding rainbow reflections, mesmerizes and evokes associations with magic and the unknown. This is a stone not for everyone, but certainly for those who want something unique and powerful.

Black opal is a variety of precious opal, characterized by a dark, usually black background color, on which shimmering rainbow reflections are visible. These flashes are created when light passes through thin layers of silica in the stone, interfering and splitting into the visible color spectrum.

Chemically, black opal is hydrated amorphous silica (SiO2-nH2O). The water content of the stone can vary from 1 to 20%, which affects its hardness, brittleness and luster. Black opals have a hardness of 5.5 to 6.5 on the Mohs scale and are relatively brittle, so they require careful handling.

Opals are a group of precious minerals that belong to the silica family. They are distinguished by their characteristic iridescence effect, i.e. the shimmering of colors in the light. This effect is caused by the interference of light in microscopic layers of silica and water.

There are many different varieties of opals, each with its own unique characteristics. Among the most popular are:

Precious opal: It is characterized by vivid opalescence and high hardness. It comes in a variety of colors, including white, black, blue, green and pink.
Milky opal: It has a white or milky color and delicate opalescence. It is softer and more brittle than precious opal.
Fire opal: It is characterized by a red or orange color and strong opalescence. It is rare and valuable.
Dendritic opal: Contains inclusions of manganese or iron that form distinctive, tree-like patterns.

What makes opal valuable?

The value of opal depends on many factors, such as:

Color: Opals with vivid and distinct opalescence are the most valued. Black opal is especially valuable because of its unique appearance and rarity.
Transparency: Transparent or slightly transparent opals are the most valuable.
Pattern of opalescence: The more regular and striking the pattern of opalescence, the higher the value of the stone.
Cut: A well-cut opal can significantly increase its value.
Origin: Opals from certain regions, such as Australia and Ethiopia, are more highly valued than others.

Why are opals black?

The black color of opals is caused by the presence of tiny inclusions of carbon, dust or other minerals in layers of silica. These inclusions absorb light, which gives the stone its dark color. In addition, black opal is often found in volcanic rocks, which are rich in dark-colored minerals. These minerals can also contribute to the stone's black color.

"Play-of-Color," or "color play," is an optical phenomenon characteristic of opals that involves the shimmering of colors on their surface. The effect is caused by the interference of light passing through microscopic layers of silica and water in the stone.

These layers have different thicknesses, causing light of different wavelengths to be scattered and reflected differently. The result is the observation of shimmering colors that can span the entire visible spectrum, from red to purple.

"Play-of-Colour" is one of the most characteristic features of opals and accounts for their unique beauty and value. The intensity and pattern of color shimmering can vary depending on the type of opal and its structure.

In addition to its aesthetic value, "Play-of-Colour" also has symbolic significance. In many cultures, opals are associated with magic, luck and intuition. It is said that their shimmering colors can reflect different aspects of the human soul.

The most famous black opals are mined in the Wollo province of Ethiopia. The volcanic rocks there hide these precious stones, which impress with their deep black color and shimmering reflections.

However, it should be noted that black opals are very rare and difficult to find.
