What is your definition of ‘Eye-Clean’?
The Whiteflash baseline definition of eye-clean is:
No inclusions visible to the naked eye of a person with 20/20 vision when viewing the diamond in the face-up position at a distance of approximately 10 inches under normal overhead lighting .
Distance, lighting and human vision all influence this judgment. There is no universally agreed upon definition of eye-clean in the trade so we developed this one in order to communicate meaningfully with our customers. 10 inches is the ‘distance of most distinct vision’ as defined by the field of optometry. It is also a basis used by the AGS Laboratory in light performance grading, and so this is a logical standard and a practical baseline.
Diamonds graded by AGS and GIA with clarities of VS or above are almost always completely eye-clean by the above standard. On our website diamond detail pages you will find a determination of whether the diamond strictly meets our standard (/Eye-clean = Yes" . Many diamonds that are not technically eye-clean may still be well worth considering as the inclusions will ususally not be seen except by very careful examination. In these cases the eye-clean field will say "inquire" and allow you to call or chat in to one of our consultants for a detailed description of the clarity characteristics and to determine if the diamond might meet your particular needs.
