Origin and History: 

Black Opal is one of the most valuable and rare forms of Opal. It is found in only a few locations globally, which include Lightning Ridge in Australia, the most famous and well-known place where Black Opal is found. The Lightning Ridge Opal fields were discovered in the late 1800s, and since then, they have been a significant source of various types of Opals, including Black Opal.

The Black Opal from Lightning Ridge is considered the most valuable and sought-after due to its unique qualities, such as its deep and vibrant colors, which are not found anywhere else in the world.



Formation and Properties: 

Black Opals are formed under unique geological conditions. They are made up of tiny silica spheres that have been packed tightly together onto the matrix over millions of years through volcanic activity. The silica spheres are arranged in a regular pattern, which refracts the light to create the unique play of color and brightness that Black Opals are known for.

Black Opals have a hardness of 5.5-6.5 on the Mohs scale, making them relatively soft and delicate, and they require proper care to avoid damage or scratching. They have a specific gravity ranging from 1.98 to 2.20 and are usually cut into cabochons to showcase their stunning play of colors. The colors of Black Opals are a result of the light diffraction caused by the silica spheres that make up the gemstone.

The colors range from blue, green, red, orange, yellow, and purple. The intensity and vibrancy of the colors depend on the thickness and arrangement of the silica spheres. Black Opals are named due to their dark body color, which provides a contrasting background to the play of colors.
