It has one single pinpoint near the girdle so I can identify it, but otherwise it's spotless.
This is the perfect clarity for me ... mind clean.![]()
I don't mind that I could have bought a much larger stone for the same budget.
It wouldn't be mind clean to me.
That said I have some colored diamonds with low clarity.
I don't mind it in FCDs since the color takes priority and certain colors are very rare.
In rare colors I'm lucky to have found any specimen I could afford.
kenny, I have a question for you![]()
Since FCD have body color because of vapors of other elements (as far as I understood, and please correct me if I am wrong), are they also often more included than clear stones? I am thinking about vapor + proximity of other elements might encourage the formation of other crystals and minerals
In naturally colored diamonds the color is the result of various things.
Boron 'contamination' causes blue, nitrogen in yellow, crystal lattice deformation in pink and browns (probably) and exposure to radioactivity causes green.
None of these color-causes is an inclusion.
I can not say authoritatively whether colored diamonds are less or more 'included' than D-Z diamonds.
I can say that inclusions affect the value of FCDs proportionally less than they do with D-Z diamonds.
Many FCDs costing hundreds of thousands of dollars are heavily included.
The most picky collector must care less about inclusions because of the rarity of FCDs, especially certain colors.
I have no clue whether any of these color-causing 'contaminants' encourage the development of inclusions.
I have read quite a lot about FCDs and have not encountered that theory, but perhaps I will in the future.
ETA: In green diamonds radiation results in not only in the green color, which usually is only near the skin of the diamond and appears blotchy but occasionally extends deeply into the diamond and appears even, but also in brown radiation stains that are left unpolished on the skin of the diamond (naturals).
I have seen GIA reports indicating the clarity grade was set as a result of these stains. (no other inclusions)
These stains are not polished off because it is where GIA looks to determine whether the radiation happened in the earth or in a lab.
