They grow under tremendous heat and must be transported to the earth’s surface in less than an hour or two by volcanic activity. In a way, diamonds are snap-frozen. If the journey is too long, the stone may return to its graphite form or carbonaceous gas.
Other atoms, sometimes, get trapped in a diamond during its violent journey to the surface. Nitrogen is the most common and even the tiniest amount causes absorption of blue light that lends the diamond its yellow color.

As per stats, more than 5000 classifications of raw diamond are possible and one can sort them according to gem quality, industrial quality and crushing boart.
Usually, they accompany a lower price tag as compared to polished diamonds, but very few are able to pass the gem-quality standard and qualify to become rough diamonds. To be precise, only 20% of the diamonds removed from the earth in natural state every year possess gem-quality. The remaining 80% have inferior quality and popular as industrial diamonds.
The criteria to choose rough diamonds are different from the selection of polished diamonds. While cut, color, carat and quality are the 4C’s to determine the …
