Question

write a note on black diamond ​

Answer 1

Answer:

In other words, natural black diamonds are a combination of two different types of pure carbon. On the ground, they can look like pieces of charcoal, which is why they're called carbonados. Currently, the main sources are Brazil and the Central African Republic.

Answer 2

Answer:

They are not a coloured diamond

While white diamonds are clear, sparkling stones, black diamonds are opaque. This is caused by the high amount of inclusions, or clusters of graphite, in the diamonds. The high levels cause the gem to appear black. Unlike white diamonds, black diamonds don't shine by reflecting light
