The Mystery of the Black Diamond

Carbonados, also known as black diamonds, are unique geological formations discovered in 1841. Unlike typical diamonds, they are aggregates of microcrystals, making them tougher and more suitable for industrial use. Their origin remains a mystery, with theories ranging from meteorite impacts to interstellar origins. Carbonados are found only in Brazil and the Central African Republic, suggesting a possible extraterrestrial source.

What makes carbonados different from typical diamonds in terms of structure?

• They are made of a single crystal.

• They are aggregates of microcrystals.

• They are softer than regular diamonds.

• They are transparent.

Why are carbonados considered more suitable for industrial purposes than regular diamonds?

• They are easier to find.

• They are less expensive.

• They are more colorful.

• They are tougher and resist shattering.

What is the main reason scientists are interested in studying carbonados?

• Their mysterious origin.

• Their abundance on Earth.

• Their unique color variations.

• Their potential use in jewelry.

Which theory suggests that carbonados might have an interstellar origin?

• Radiation transforming carbon in the mantle.

• Deposition via asteroid from space.

• Meteorite impacts on Earth.

• Formation in subduction zones.

Where are carbonados primarily found on Earth?

• Australia and India.

• South Africa and Botswana.

• Brazil and the Central African Republic.
