A photo taken in the Labrador Sea shows a black iceberg shaped like a diamond. The discovery attracted the attention of social media and glacier experts.
The image was captured by a Canadian fisherman who was sailing more than 100 km (62 miles) from the coast. According to specialists, very few humans have seen anything like this.

What is a black iceberg and why does this phenomenon occur?
Icebergs are usually white or bluish. This is due to the air bubbles inside them, which reflect light evenly.
Over time, that air is compressed and expelled. This way, the ice becomes more transparent and allows more light to pass through, resulting in a bluish hue.
Dark materials, volcanic ash, or meteorites
The black color may be due to the presence of sediments, volcanic soot, or even remnants of a meteorite. These materials can adhere to the ice as it rolls over a contaminated surface.

The block captured this time is estimated to be between 1,000 and 100,000 years old. Its color and unusual shape make it an extremely rare case.
What do experts say about this iceberg?
Researchers agree that this type of formation is very rare. Its scarcity means that there isn't enough scientific information about its exact origin.

However, publications such as Science Alert provide theories about the presence of minerals or volcanic residues inside it.
