The other way is to treat the clarity of diamond. This can be done with polishes, drillings, laser drilling, ejecting glass like substances into the diamond, laser burning of carbon spots, and so forth. In most cases a treated diamond will come out much better looking than what it started out as, and is commonly being used all across the world to enhance substandard clarity diamonds. All of it is legal as long as you make sure the purchaser knows about it. When it comes to cleaning a treated diamond you have to take a few additional precautions and steps other wise the clarity enhancement will actually come out.
