I know that *some* of us ( ) still struggle to get good photos of our older stones. If you can coach a seller to take decent photos, surely you can teach a motivated PSer!! And, for anyone who is evaluating a stone, being able to post good photos here would certainly help the experts in their assessment. Thanks!

I think it would be a negative thing only for people who want absolutely purely vintage, in which case buying a loose stone (not sent into an original vintage setting) doesn't really make sense. Otherwise, what's bad about getting a stone with a clean girdle and no chips? As you know, I'm more on the "let's quickly polish out the chips" side

The benefits of buying from such vendors is accuracy of information and certainty about what you buy. The down side is that the diamonds cost much more than diamond bought from other sources and the diamonds have often (I would suggest usually) been repolished or recut in some way to clean up nicks and chips to the girdle (at best) or to "improve optics" with a full-body overhaul (at worst).
But many old cuts are offered by estate sellers who may specialize in diamonds, they are offered for private sale, or they are offered at pawn shops And in many of those cases, the sellers do not have accurate information about what they sell other than an "appraisal" of limited value, and in the majority of cases the diamonds are set into vintage mounts and sellers do not want to unset the stones. The benefits of this way of buying is sometimes a lower price (yes, I am very sure of this, the old cut market is decidedly different than the modern RB market) and greater assurance of an original, untouched cut stone (no guarantees though!). The downside is uncertainty about what you are buying.

Some people desire un-retouched old cuts for a variety of reasons, not only because they come in vintage mounts. A large part of my enjoyment of my old cut is knowing it was cut a long time ago without the help of a computer to model the best use of the rough, for example.
That issue aside, the uncertainty is the downside, to me, not the actual practice per se -- though people vary in their opinions on the practice of fixing up old cuts on a continuum. But in my opinion, when you don't know what has been done then you can't even exercise your own right to have an opinion. This is not an issue of recutting or not recutting, but rather of knowledge, marketing, and provenance of a stone.
I have already made this argument, but a huge part of the "value" of old cuts is that they were cut a long time ago -- this fact is used to sell the romance of old cuts and also to appeal to cut aficionados. So I think that potential unknown "work" on a stone prior to buying is a down side for consumers, and not only from a "purity" perspective -- the value of an old cut might be affected by its recut status if that status was known and the recut was substantial. For diamonds cut today with the help of modern technology, many people would have MUCH higher standards for cut quality, for example! The same "old cut" could then have very different market values if it was truly cut 80 years ago compared to if it was cut this year, depending on how ideal its optics were.
I readily accept leakage in a diamond cut 80 years ago. Would you readily accept leakage and lazy facets in a diamond cut in 2013?

My diamond is about 8mm in diameter, which for an old cut is spready so I thought it might be bigger than 2ct! I unset the stone and weighed it and... drumroll.... it was 1.89ct. So clearly, the vendor had seen the diamond loose and then had poorly reset the stone. And of course they saw it loose. They NEEDED to know if it was over 2ct or not, just like the seller of your diamond would have NEEDED to know if it was over 3ct. So, it was my experiene that made me think yours has also been seen loose.
And, my seller had super washed out photos like yours aimed at obscuring the color. Once unset, my stone is a K/L SI2. Not the G Si1 represented by the very reputable estate ebay seller. ETA: I should say my diamond masks its body color very well, my appraiser guessed it at I color face up when set. So if I did not know that the seller had seen the stone loose, where its body color is much more noticable, then I might have excused the mis-grading on the "appraisal".
So, after that and a couple other experiences, I have my own way of interpreting ebay grades for color and clarity that are based on seller opinion or in house appraisals (i.e., most estate sellers).
"GH" in ebay speak means I/J/K.
"J/K" means M/N/O.
"K/L" in ebay speak means "Faint Yellow" (i.e., N-Q).
And there are only three ebay clarity grades.
"VVS/VS1" means the stone is likely eye clean, but beyond that who knows.
"VS2/SI1" riskier buy, maybe SI1 but could be SI2.
"SI2/I1" run away, this has huge eye visible inclusions.
Its another story with private sellers. Their appraisals can be quite accurate.
