OEC question... prong reflection under the table - how?

[GemFever]

Dear cut experts,

I came across a pic of an OEC that has a prong reflecting under the table. From the pic, as far as I can tell, the cut isn't awful. So how does a prong get under the table? Does it have to do with the chips in the girdle? Maybe it's a shallow cut? Just very curious how this happened.

Thanks!

Chips shouldn't have anything to do with that. It's likely a shallower stone, or the angle of that area is just at the wrong degree so it's totally see thru. Any possibility that may be an inclusion? It is odd that the prong would be SO visible in that one particular area, given it looks well cut enough everywhere else. I have a lot of shallower old cuts and none of them show so much see thru!

I think that maybe the ring is reflecting off of the camera lens, which is then mirroring the prong back onto the pavilion. Otherwise, I don't see how the top of the prong could be reflecting in there.

If it was reflecting off the camera lens, you'd see the lens reflected clearly. It looks like the base of the prong is seen thru the diamond.

Thanks for chiming in, I'm stumped too. I asked the seller what kind of an inclusion it is (because I just couldn't figure out how a prong would reflect like that), but she said it's a reflection. I'll add more pics. The dimensions are 7.55 x 7.52 x 4.12. Does that indicate shallowness?

Thanks again!

Darned shallow at 54% which I think is the cause of this seethrough prong issue. An antique cut needs to have the necessary depth to work with and even for a modern round, it will be considered shallow.

Mystery solved, then; money saved

Thanks!

Its a prong tip, not base, in my opinion. Reflecting the underside of the prong on the pavilion mains.

Its shallow, but it looks good in the pics. I know that stone. Its worth considering. It would need a girdle polish but the table is very small which can make a shallower stone perform well (e.g., Kelpies stone is even shallower). Price is right. I was tempted

Dreamer,
It looks like a prong tip to me too, because it is the bulbous part. What I don't understand is why is the top of the prong reflected? Or is it the underside of the prong tip that is being reflected?

 

[GemFever]

Oh dreamer noooo.... I was about to let go of even thinking about it. Gonna start thinking again, then

How about this - with a shallow stone, you are going to get a tilt window more easily

Hmm hmm... what do you guys this of this one? I'm wondering why it hasn't sold, besides the inclusion. I don't mind this kind of inclusion (it's tidy and off to the side, in my view)... but are there other problems?

The inclusion looks like a surface reaching feather, spanning two crown facets and in into the corner of the table. That's not a risk I'm willing to take!

 

[GemFever]

Thanks for the explanation ForteKitty, and everyone for input. I'll pass on both stones, since I'm not in a rush and just looking for a nice old stone (for a good price) for a future pendant. Gotta cool off on the eBay rush.

Cheers!

Ditto this.

Chrono I also thought it was a prong tip, maybe the underside. But who knows!
