Answer
HI JOY,

IT SEEMS THAT THIS IS A SERIES OF QUESTIONS FOR A CLASS IN DIAMONDS. GRAINING IN DIAMONDS IS CAUSED BY A DISTORTION IN THE CRYSTAL LATTICE WHEN THE DIAMOND CRYSTAL IS FORMING. THE CAUSES ARE MANY, HEAT, PRESSURE, ANOTHER CRYSTAL FORMING IN THE SAME SPACE ETC. A PICTURE OF THE GRAINING IS HARD TO SEE AND I DON'T HAVE THE TIME OR PHOTOS TO SHOW THIS PHENOMENON. YOU WILL NEED TO TAKE A DIAMOND GRADING COURSE TO EXPERIENCE IT. SYNTHETIC AND NATURAL DIAMONDS HAVE THE EXACT SAME PHYSICAL PROPERTIES AND THERE IS NO PARTICULAR SHAPE FOR A SYNTHETIC DIAMOND. SYNTHETIC AND NATURAL DIAMOND ARE CONSIDERED ONLY AS "DIAMOND".
