These are two of my OECs. Both show leakage under the table. On the left, the leakage appears yellow/gold, which is the yellow gold mount showing through. On the right, the leakage is black because the inside of the mount has scorched dirt lining its basketThese photos show the leakage at its worst. In person, moving your hand, with both stones you cannot really see it. But it is apparent, particularly when looking at the stones from certain angles. It is the most common "issue" I see with old cuts (my sample size is 12). ETA: These are both very beautiful true old cuts, excellent examples of their type IMO.
The black and some of the grey(arrow heads) is clearly obstruction from the camera lens.ChrisES|1336588202|3191288 said:Let me offer another picture I'd be curious about. It's my fancee's stone, taken in a homemade lightbox (and posted on PS before). Insofar as the slight transparency is visible all the way around the stone, I think it's leakage rather than tilt, but I think it's less leakage than is seen in the photos Dreamer_D posted. What do you think?

Slightly deep pavilion, not likely to be a large amount of eye visible leakage but the reflectors would likely show some.TitanCi|1336589761|3191321 said:I would love to see examples of leakage. I know this subject is like beating a dead horse, but it's interesting.
The stone in the first picture has a CA of 35.0, PA 41.2, table 56, depth 62.8. Based on the specs, now, does the stone still fair well?

If so, why?

Wow. That's really bad!Laila619|1336591799|3191376 said:Here is a great example of major leakage that even a novice would be able to see:
You can see skin right through the diamond.David, you can't argue with this one, lol.

Simple as that.

Good photo of a badly cut RBC Laila- it's definately displaying an unattractive leakage pattern!!
But my request was for a GIA Triple EX, of AGS0 cut grade stone showing detrimental leakage.

Interesting Karl- you're suggesting that "invisible leakage" somehow detracts from a stone- or that such a property removes the possibility of it being considered "the best".
OR- the way I read it- innocent consumers asking a question are led to believe they should spend more for something they can't ever see......simple as that.

The less bright areas are likely a mix of obstruction and a reflection of the environment along with some weaker white light return. Maybe just maybe partial leakage in some spots.
I don't see any major leakage areas that I am 100% sure about.
Repeat your test using a bright red background to see any leakage that may be present.

many consumers also want VVS or D stones even if they are spending more for something they can never see.
I have seen consumers advised that minor leakage in reflector images should not be visible with stereovision.
