I attempt to accurately represent and describe cut stones and rough
as to appearance, size, origin and fully disclose any known
treatments in its description. Because you view the images on a
different monitor with different settings, color is particularly fickle
to represent, but I do my best.
|Grading System for Colored Stones
IF (internally flawless) = Free of inclusions under a 10x loupe magnification
VVS (very, very small inclusion) = Very small inclusion(s) under 10x loupe magnification, difficult to find.
VVS2 (very, very small inclusions) = A few, very small inclusions under 10x loupe magnification, difficult to find.
VS (very small inclusions) = Very few small inclusions recognizable by an expert under 10x loupe magnification.
VS2 (very small inclusions) = Some small inclusions recognizable by an expert under 10x loupe magnification.
SI (small inclusions) = Several small inclusions easily recognizable under 10x loupe magnification, but not diminishing the brilliance
appreciably. This is what I would call "eye clean" but this term is often abused.
I (inclusion) = Inclusion(s) easily recognizable under 10x loupe magnification, but not diminishing the brilliance appreciably.
P1 (1st Pique) = Inclusions at once recognizable under 10x loupe magnification, but not diminishing the brilliance of the stone
P2 (2nd Pique) = Larger and/or many inclusions, slightly diminishing the brilliance, recognizable with the naked eye.
P3 (3rd Pique) = Large and/or many inclusions diminishing the brilliance, easily recognizable with the naked eye.
None Known - No known treatments, please note that there could be a very small possibility of some treatment done that I am
unaware of at the mine or before I aquired the rough/stone. In general there will be no treatments of any kind in this catagory.
Heat - Heat only. Heating is a fairly common practice and it is done to lighten or eliminate an unwanted color in some rough/cut
stones. I personally do not find heat an issue, but it should be noted.
Unknown, but likely heated - I do not know of any treatments, but this type of rough/stone is often heated.
Irradiated - Irradiation is used to change or improve the color of a cut/rough stone.
Uknown - I have no idea if any treatments have been done.
If you have any questions, please inquire.
