Natural diamonds originate from deep within the Earth's mantle, formed under high pressure and temperature conditions over millions of years.
Diamond are only scratched by diamonds.
Natural diamonds are formed deep within the Earth's mantle when carbon atoms are subjected to high pressure and temperature over millions of years, causing them to crystallize into diamond structures.
There is an estimated total of about 1,200,000,000,000 carats of diamonds on Earth, which is roughly equivalent to 240,000 metric tons. Most of these diamonds are located deep within the Earth's mantle and are not easily accessible.
A geologist would differentiate between a natural diamond -- formed by a geological process, and a synthetic diamond -- formed by a man-made process. Both diamonds are 'real diamonds'. Read more about synthetic diamonds, below.

Some raw diamonds appear to be pyramids, or a pair of pyramids joined at the base. The edges are not sharp and these descriptors only approximate the shape of the natural stone. You can follow the link, below, to learn more about raw diamonds.
Natural diamonds can be industrial diamonds or gemstone quality diamonds. Gemstone quality diamonds are worth more than industrial diamonds. If by 'industrial', you mean man-made, then a natural diamond will always be more valuable than a man-made diamond of equal carat weight, unless the natural diamond is not of gemstone quality.
Yes - diamonds occur naturally in nature. Humans refine their shape to produce gemstones.
Loose blue diamonds are expensive to buy and are normally bought in good jewelers or online. The distinguishing features of loose blue diamonds are their natural blue tint and shape of the diamond.
Well, diamond may be burnt, or crushed -- something you probably wouldn't want to do to a gemstone. And the common shapes of gemstone diamonds are man-made choices, not the natural crystal shape. So, yes, diamonds lose their shape with intense chipping and polishing.
Diamonds are shaped by diamond cutters using diamond-tipped cutting tools and following a plan for the raw stone to maximize its natural colour, clarity and carat weight.
