diamond are prized for their unfeelingness . In jewelry , they can last generations and baulk simoleons during 24-hour interval - to - day vesture . As blades or exercise bits , they can penetrate almost anything without getting destroyed . As a powder , diamonds shine up gem , metal and other materials .
So is anything harder than rhombus ? It turns out , figure out the answer is , well , a number intemperately .
Diamonds can scratch almost everything, but can anything scratch a diamond?
For most pragmatic purposes , diamond is still the hardest material , saidRichard Kaner , a materials pill pusher at the University of California , Los Angeles . There are ways to make diamonds that are heavy than stock treasure baseball diamond . And there are other material that might theoretically be harder than diamond , but they do n’t subsist in a strain that you could keep back in your hand or use wide .

While anyone wearing a baseball field ring can testify to the quartz ’s lastingness , it ’s of import to understand that " hardness " have in mind something very specific to scientist , saidPaul Asimow , a geochemist at Caltech . It ’s often confused with other qualities , like gracelessness or military strength . These factors sometimes , but not always , correlate with hardness .
Diamonds can scratch almost everything, but can anything scratch a diamond?
Diamond , for example , is very heavy but only moderately stiff . And it ’s astonishingly easy to break : It shatter easily along its crystal boldness , which is how gem cutters can make beautiful , miscellaneous diamonds that sparkle .
Scientists measure hardness in a few different ways . Geologists often rely on a relative metric address the Mohs severeness scale , a direction to describe minerals in the field free-base on whether they can scratch each other . Diamond is a 10 — the top of the scale — meaning it can scratch almost anything . Soft , friable talc is 1 .
In the science laboratory , stuff scientist rely on a more exact measurement call the Vickers hardness test , which determines the hardness of a textile based on the effect required to dent it with a pointy baksheesh . ( To visualise this , imagine drive a pencil into a rubber eraser . )
Diamond is made up ofcarbonatoms arranged in a cubic latticework , held together by forgetful , potent chemical substance bond . This structure gives it its famous hardness . Most materials that claim to be harder than diamond come from slightly vary the classic baseball diamond vitreous silica social system , or swapping out some of the carbon atoms with mote such as boron or nitrogen .
A prime rival for a material unvoiced than diamond is lonsdaleite . Like ball field , lonsdaleite is made up of carbon atoms , but they are arranged into a hexangular crystal structure instead of a three-dimensional one .
" Lonsdaleite is very puzzling , " Asimow assure Live Science . Until recently , it had been found in such tiny quantity , mostly inside meteorite , that it was n’t clear whether it counted as a brook - alone material or if it was just adefect in the stock rhombus crystal body structure .
of late , a squad of scientists foundmicron - sizing lonsdaleite crystals in meteorites — still lilliputian , but much big crystals than late finds . That ’s collapse the mineral more credibility , Asimow said . Other scientists have reportedmaking lonsdaleite in the lab , though the watch glass existed for only a fraction of a minute .
So lonsdaleite is intriguing , but it wo n’t be replacing diamond for app like press clipping , drill or polishing anytime before long .
Playing with diamond ’s nanoscale bodily structure can also make a fabric that ’s harder than a veritable diamond . A textile that ’s made up of many tiny diamond crystals will be knockout than a gem - timber rhomb that ’s a individual lechatelierite , because the nanoscale grains lock up instead of moving past one another . " Nanotwinned " diamonds , in which the grains form mirror - image patterns of each other , are reportedlydouble the hardness of even diamonds .
At the end of the day , though , most scientists are n’t pursuing superhard materials solely to fructify records — they ’re trying to create something useful .
" material scientists spend a lot of time inventing superhard materials that can be made at scale , " Asimow said . " And for many purposes , being harder than diamond is not the design criterion . " Scientists might desire something almost as hard as diamond , but cheaper or easier to make in the lab .
— Can rhombus burn ?
— Why is gold so soft ?
— What is the rarest mineral on Earth ?
For example , Kaner ’s research laboratory has create a assortment of superhard metals that could be used in industrial applications in stead of diamond . One that’snow available commerciallyis acombination of tungsten and boron , with a few other metals sprinkled in . The form of the crystals give the material different dimension in dissimilar focussing — so , when held in the right orientation , it can rub a diamond , Kaner tell Live Science . It ’s also more affordable to make , in part because it does n’t require the high pressure level conditions used to make baseball diamond in the laboratory , he noted .
So while baseball field in its many forms still rule the roost in terms of harshness , the classical textile might face other challenges to its throne go forward .
