Why are there black diamond?
Why are they black?
How are they formed? How do they differ from White diamond?
Charcoal, graphite and diamond are all made of
the Carbon element.They are so different due
to their differences of molecular structures.
What is called "black diamond" is in a transitional
carbon state between graphite and pure diamond.,
says a famous gemologist (gem specialist) called
Steven Hoffer. A black diamond gem is very
rare, they are also very hard and beautiful.
More common are the white diamonds with
black insertions, the black material is little
pieces of coal, an imperfection formed
during the crystal formation, and it makes
the diamond much less valuable.
Thanks for asking NEWTON!
