A natural diamond is more rare than a manufactured diamond.
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.
If you are not a jeweler than the best way is to ask for gemological report at GIA, EGL, IGI. Which will confirm the origin of diamond and it's characteristics. For more information on synthetic diamond follow my link below.
According to Wikipedia: "The bulk modulus of superhard phase nanotubes is 462 to 546 GPa, even higher than that of diamond (420 GPa for single diamond crystal)." Note that diamonds are natural minerals; nanotubes are fabricated, making diamond the hardest known natural substance. You can read more about nanotubes, below.
=>diamond is not conducting electricity and heat. =>it is hardest natural substances known. =>it occurs naturally free state. =>graphite is soft and greasy to touch. =>it doesn't conduct heat an electricity. =>it occurred naturally and manufactured artificially. =>buckminsterfullerene is used in medicines. =>it is used in treatment of cancer.
It really depends on the cut, clarity, color and carat weight of the diamond. Some colored diamonds maybe more expensive based on the above factors and some colorless diamonds maybe cheaper based on the same factors. Where the diamonds are sourced from and whether they are certified also has an impact on the cost.
Yes, if it is pure natural sapphire it will be worth more than a diamond.

I think you are asking if a natural clean diamond is worth as much as a natural diamond that is Not considered clean? The answer is no. A clean diamond means that it is clear from imperfections. Now this can mean clear to the naked eye, or clear under a microscope. Of course the diamond that is clear under the microscope is much worth more than a diamond that is only clear to the naked eye.
A natural blue diamond will always be worth more than a white or colourless diamond, given equal carat weight, clarity, and excellence of the cut.
Mined diamonds are more valuable than manufactured diamonds, as gemstones. This may not be a consideration for you, in which case, you would own a manufactured diamond.
A human life, for example, has more worth than a diamond.
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.
The term 'genuine, clean diamond' implies a generalist's description of what a gemologist would term 'natural, acceptably flawed diamond'. The term 'regular diamond' is as descriptive as 'regular human'. Any diamond is worth what someone will pay you for it.
Yes. Any diamond is worth more than a crystal.
Your question is based in semantics, the key word being 'genuine'. A genuine diamond means an authentic diamond. Even mankind can manufacture an authentic diamond, given the carbon materials, heat, pressure and time. Gem quality diamonds are evaluated according to the carat weight, colour, clarity and cut. Colour and clarity can be 'adjusted' by mankind, which lowers the value of an authentic diamond. A natural diamond formed deep within the earth's mantle, erupted to the earth's surface in a volcanic pipe, mined, brokered, cut and polished as a gemstone, that has not been adjusted or enhanced, is worth more than a diamond that has been altered or manufactured by mankind.
Both kind of diamond are made from carbon. Mined diamonds are formed by Mother Nature; manufactured diamonds are formed by machines in a laboratory. Both rate 10 on the Mohs scale of hardness. A natural diamond will be much more highly valued than a man-made diamond, given that both are gem-stone quality. As with mined diamonds, most manufactured diamonds have industrial applications, and are not used as gemstones.
Platinum is not more expensive than a beautiful, natural diamond.
