how do you think they cut diamonds?\n\nthey're CLEAVED. If you hit a diamond at a certain angle it will cleave off and break. If you hit it with enough force, yes it will shatter.\n\nDiamonds are the hardest substance on earth. Hardness and resistance to compressive forces are two totally different types of things. \n\nI can smash both a diamond and a rubber ball with a very high force. If the rubber ball does not shatter and the diamond does, does that mean it's stronger then the diamond? No. It just means that it can wihtstand compressive forces better.

Naturally this depends on what type "dirt" you are sifting.   Diamonds are typically only found in certain types of "dirt".  The most common type of diamond-containing material is a clay mineral called Kimberlite, sometimes found in tube-like structures associated with volcanic activity.  Your chances at finding a diamond will also increase if you are sifting "dirt" that once was at great depth underground, where geo-pressure was high enough to create the crystal.  If you are sifting "dirt" from, for instance the California desert, pack a lunch.  You'll be at it a while

it doesnt really matter. but when your on a soft surface its better for your back. when your on a hard surface it can be bad for you back. so i think soft is better.

g-string. less material to go up your butt. They look sexer too.

What kind of mud?  Butt-Mud?

Well is there Kimberlite in the mine? Is it ultramafic rocks formed at phenominal heat and pressure? No? Then you aren't going to find a diamond in that mine if you would have in the first place. There's a reason they're rare.\n\nAnd beeswax? Nothing. That's not going to help you unless you want to use it to stop up your ears to drown out the machinery noise. Actually that's a good plan. You don't want to loose your hearing.

Mohs based the scale on ten minerals that are all readily available except the last one, diamond. The hardness of a material is measured against the scale by finding the hardest material that the given material can scratch, and/or the softest material that can scratch the given material.\nThe Rockwell scale characterizes the indentation hardness of materials through the depth of penetration of an indenter, loaded on a material sample and compared to the penetration in some reference material.\nThe B-scale is used for softer materials (such as aluminum, brass, and softer steels). It employs a hardened steel ball as the indenter and a 100kg weight to obtain a value expressed as "HRB".\nThe C-scale, for harder materials, uses a diamond cone, known as a Brale indenter and a 150kg weight to obtain a value expressed as "HRC".\nThe depth of penetration is converted to a scale in which the harder the material the higher the number.\n\nThere is a third test called the rebound hardness test, using the Bennett Hardness Scale.

the Mohs scale is a scale of hardness for gem material only and it goes by what will scratch what, like diamond at 10, corundum(sapphire and ruby) at a 9 and so on down the scale.  there are not equal increments between the numerical ratings either and scale does not apply to metals...  titanium will scratch very easily and really cannot be refinished while tungsten is extremely scratch resistant.

It all depends on the metal.\n\nSome metals are soft in nature, but when alloyed with others can become very hard and strong.  Combining iron and carbon with Molybdenum and Nickel can make a very hard, but brittle steel.  \n\nCopper by itself is very soft and easy to work.  Combine it with tin and you get Bronze (a harder metal) or with antimony to get brass (harder still).\n\nHeat treatments also affect the hardness.  When a metal is heated, the crystals essentially "reset" themselves to be in an amorphous state.  A rapid cooling such as a water or oil quench will cause small, tightly packed grains, creating a hard metal.  A slow cooling will result in a softer material that is easier to work with.

grade five is the highest grade (more perfect in roundness and quality).  ceramic is harder than steel and roll smoother and wear slower.  it costs more, but worth the price, unless you pack your hubs frequently.

because those are more padded and softer

Diamond is the hardest known naturally occurring material, scoring 10 on the relative Mohs scale of mineral hardness and having an absolute hardness value of between 167 and 231 gigapascals in various tests. Diamond's hardness has been known since antiquity, and is the source of its name. However, aggregated diamond nanorods, an allotrope of carbon first synthesized in 2005, are now believed to be even harder than diamond.
