diamond in the form of a diamond paste applied to the cutting wheel.

"bone is the strongest material."

The word strongest has many meanings. An elastic band has incredible elastic strength, a diamond has incredible hardness. A carbon fibre has excellent tensile strength.

Titanium, for instance, is renowned for it's strength versus weight, but it also mauls more easily than high alloy steel.

It also depends which direction the force is applied in. Carbon fibre has terrible strength when in compression.

Sorry but in order to avoid any misunderstanding, I said that diamond is the HARDEST material known to man not the STRONGEST so what 'bone', 'carbon fibre', 'titanium' and the like have to do with this statement I really don't know.

Diamond is known as the hardest natural material known to man.

Indeed rubbing diamond against diamond will wear both out which is why the wheel which has the diamond compound stuck to it must be replaced on a regular basis.

This stands to reason as the both are being worn away but only the diamond gem is the one which is not to be replaced.

As science evolves probably one or other synthetic material will be developed so in view of this I will simply say that "diamond is the hardest NATURAL material known to man" just to set the record straight so to speak

Diamond is indeed the hardest material known to man and can only be worn away with diamond.

The wheel is impregnated with a specially prepared diamond 'paste' and it is this 'paste' which is wearing or cutting away the main diamond forming the facets.

They do indeed use laser technology but for the smaller stones. The larger expensive goods are better done bvy skilled cutters.

The 'record thing' is called a schijf (disk in flemish) and it has a special diamond mixture of powder and borax which cuts the diamond. It will cut the finger if pressed hard against it.

i feel like masturbating after watch this video

@spacebrdcst im pre sure that they use some kind of think covered in diamond dust to cut em but im not totally sure

[spacebrdcst]

If the Diamond is the hardest matter on the Earth, then what material is used to cut them?

[mrliampep5i]

just put 3 diamonds in a row two sticks at the bottom and there! you got a pick axe

@lexichronicle2 bone like pearls are not as hard as diamonds and can be scratched easily by the fingernails.

@georgezaidmann "Sorry but in order to avoid any misunderstanding, I said that diamond is the HARDEST material known to man not the STRONGEST"

Someone else said "bone is the strongest".

@Mikeymoomah Yup, the Nobel Prize winning 'sticky tape' method of production was actually invented at a local university, who also supplied me with some quantum hall sensors to mess around with. :P

I should have said in the other comment, the grinding disc will also wear down, but the diamond on the disc is the dirty industrial kind, so it's not too important if that wears (it's used, routinely, in building tools). Diamonds are rough 'cut' (in the normal sense of the word) by fracturing them.
