This is just about the strangest thing! Next time, maybe you could ask... why ?
NO idea what this could be about (the statement is waaaay out of this world), but, could this be the story of a clarity enhanced diamond with a laser drill mark (i.e. hole) visible under magnification AFTER the sale
Actually, I remember my Mother showing me her e-ring, and telling me there was a hole right down the center of her 'blue-white' half carat diamond. I now come to realize she was speaking of an open culet...but I still don't know what she meant by 'blue-white'.
It was lovely though, fishtail prongs set in platinum, with bead set diamond side stones.
Too bad, I think she pawned it for slots money...*sigh*
Have you ever heard of a “blue-white” diamond? They are diamonds that possess blue-white fluorescence. Once considered the crème de la crème, styles have now changed, with one of the prevalent beliefs of the diamond trade being that diamonds with fluorescence are less desirable.
Despite this modernist view on this blue-white effect, fluorescence can actually greatly benefit a diamond. Diamonds with tinted color grades of H to M actually benefit from a moderate amount of fluorescence, as the effect makes the diamond look whiter.
Some people actively admire this fluorescence and appreciate its subtle blue-white effect. Whatever your opinion on the merits of blue-white fluorescence, many diamonds possess this property and they often represent exceptionally good value.
