are extracted from the earth by volcanic eruptions. diamonds");
are made out of carbon just as graphite is, which is carbon when it reaches earths stable surface. To ensure that Diamonds");
do not transform into graphite, they must be transported to the earth’s surface in a very rapid manner. diamonds");
are very rare, as only 20% of all mined diamonds");
are genuine. Diamonds");
are also the hardest gem on the MOHS scale. Ironically, graphite, which is also made out of carbon is the softest. This is due to the way the atoms in each material are linked together. Diamonds");
can be found in many places over the world, including the United States.
come in different colors, including white, silver, blue, yellow, green, brown and pink. In the traditional white diamond, the one that is most valuable will have a slightly bluish color, where the least valuable will be slightly yellow. However, diamonds");
