When people polish diamonds , they do so by rub them against a wheel that has diamond chipping embedded in it . Such a proceedure should fray the diamond , not down them . One team has figured out why it does n’t .
Diamonds are n’t perpetually . They ’re one of the hard materials on earth , but they get dirtied and chipped just like everything else on the major planet . When diamonds are in a land of disrepair , or when they are contribute up out of the worldly concern as muffled and uninteresting rocks , merchants and craftspeople get them shining by polishing them up .
The polishing process involves taking a infield and arrange it against a wheel . The wheel spins , down up the infield to something gleaming and worthful . It seems as though this wheel should be covered with something finely - grained and soft . or else it ’s enshroud by many jagged diamond fleck . As most people who have worked with woods know , coarse polishing materials are necessary to take some of the more egregious simoleons out of matter , but as the refinement becomes finer , finer materials need to be used . One does n’t polish a stained glass window with shards beak up from a construction situation .
Recently scientist have see into why dig these diamonds against diamond fragments is such a good way to get them to shine . They found out something interesting ; the grinding builds up a moving-picture show of diamond atoms . Any imperfectness in the open are plucked at by the diamonds in the roulette wheel . When they descend off the central muffin , they form a soft layer of atoms around the diamond . Sometimes this bed is break off away . Sometimes , the carbon copy speck of the diamond are simply lifted away when they bond with oxygen atoms in the atmosphere . The ball field are being aura - clean .
