||The old proverb is very apropos; rough diamonds appear to most as an interesting rock. Individuals outside the industry usually tell me if they saw one on the street they would not bother to pick it up. Natural rough diamonds grow under high pressure and high temperature deep within the earth over the course of millions of years. Under ideal situations diamonds will develop into pure carbon structure devoid of any impurities and into an octahedral shape (two pyramids base to base). However, it’s very rare for the perfect conditions to exist naturally. Therefore, rough diamond though often created in an octahedral form can occur in almost any shape and the purity of its carbon crystal structure can sometimes create diamonds of varying clarity and color. Some “impurities” can create diamonds to have wonderful colors. The element, boron, causes the very rare and beautiful blue diamond. Nature creates diamonds which are colorless and others in all colors of the spectrum some more rare than other. The rough diamond’s shape, purity, and color all factor into how it will be cut and its inner beauty brought out.
