 | | However, many of you are buying magnificent diamonds, then allowing them to gather so much soot, dirt, oil, hand lotion, soap, hair spray and grease that any benefit from buying a well-proportioned, white, eye-clean, gigantic rock is negated. |
 | | When the only benefit of a good diamond is increased light return (when clean) then dont purchase a good quality diamond if the diamond cant be properly maintained. |
 | | At the end of any given day, even the 91% diamonds will have only 67% light return due to the oil and dirt that accumulates from normal wear. |
