Carbon Inclusion Diamond. Black Spots or more commonly referred to as Black Carbon Spots are Crystal Inclusions that formed in a Diamond when the Diamond was born. Half the diamonds on the market today have eye-visible black inclusions in them.
While the literature does talk about graphite inclusions in colorless diamonds many assume that black inclusions in diamonds are all carbon graphite the only thing scientifically reaonable to say is that not all black appearing inclusions are. Black Spots also called Pepper are one of the most common Inclusions found in a Diamond. Under 100 miles deep and a 2000 Fahrenheit temperature with an exerted pressure of more than 70000 pounds per inch square a diamond with some flaws on its surface will definitely be made.
Laser lines are not a natural diamond inclusion.
These are natural blemishes or flaws. Crystal inclusions in an eye clean diamond are usually too small to pose a serious durability risk. The eclogitic suite includes diamonds with inclusions of eclogitic majorite garnet. The carbon isotopic composition expressed as normalized difference δ 13 C measured in to the international VPDB standard of inclusion bearing diamonds from worldwide sources.
