I think you are asking if a natural clean diamond is worth as much as a natural diamond that is Not considered clean? The answer is no. A clean diamond means that it is clear from imperfections. Now this can mean clear to the naked eye, or clear under a microscope. Of course the diamond that is clear under the microscope is much worth more than a diamond that is only clear to the naked eye.
Every -- each and every one -- diamond is valued by its cut, clarity, carat weight and colour. This collection of stones will be worth less than a single diamond weighing one carat.
