Bump. Arrow between 3 and 6 looks off, but is that from tilt during photo?
 
That's exactly what I was thinking, that it was leaning during the photo.
 
something weird here and i don't think it's just the photo.
Im to sick tonight to think strait so callin in some help.
 
It is a pretty decent stone, despite some light leakages, it will still be pretty bright stone. I am not a fan of crown angles below 34, because it will reduce the fire of the stone. Nonetheless, the pairing of both crown angle and pavilion angle seems to be fine for me. The arrows at the 6 o'clock and 9 o'clock positions are off slightly. And now that all of us are concerned about the arrow at between the 3 o'clock and 6 o'clock positions, it will be best to check with the vendor, and see what they say. Could that caused by inclusion, I wonder... (Not familiar with inclusions, it is just a wild guess). :whistle:. No GIA number for us to refer to?

Its not an inclusion, the blockage is too precise. Its almost like that arrow is not on the same plane as the others. @drk14 @diamondseeker2006 @gm89uk and other technical prosumers. Any theories on that arrow between 3 and 6?

@Karl_K I'm sorry you are not feeling well. Honey lemon water and sleep are my go-to for when I'm feeling cruddy.
 
My guess is that it is a cut issue. Whether it would be noticeable in real life, I don't know. I think the stone is a good one other than that, and I think you'd have to see it to know for sure. Ask your vendor for a video for starters.
 
I agree - a slight variant in one pavilion or crown main - or a bit of both.
That could be the old Idea-scope set up that had a slightly larger hole for the camer - so a tiny issue with the stone or the tilt of the stone in the tray can do that.
Not a bad stone - not near h&A's but if the price is right - it should way out perform most stones.
 
Very interesting stone.

Look first at the hearts image. This shows big time variations. This is done to get the average of pavilion angles to that 40.8 sweet spot. Remember, that’s an average of 8 facets, and the range can really be pretty big. The GIA report of the angles assumes the facets are perfectly flat, but the curves in the arrowheads would suggest otherwise.

Now look at the faceup views. There are major variations here where there should be symmetry as well. Check out the little triangular facets between the arrows. I don’t think these have a widely used name but I’m not sure. I call them the pigeon toes. These are supposed to match. Again the variety here suggests symmetry issues and, specifically, pavilion azimuth issues.

Actually, the wonky arrow at 3 o’clock is the thing I’m least concerned about. This is done in ones of those fancy photo setups where the stone and camera are fixed and the 3 faceup views click through a different reflector for each. Minor problems in the setup can look goofy in all 3. The camera body is usually black and just the right tilt can make one pavilion main show a direct reflection of it while the color in the reflector cone appears in of all the others.

It's probably a pretty enough stone, and it’s probably a GIA xxx, but it’s cut the VG boundary on every issue.
 
That arrow is just reflecting a steeper angle, IE the camera lens instead of the blue from the ASET which is slightly less steep.
 
i like the red meaning a lot of light returns but i am not too sure about the heart & arrow images

Thank you for taking the time to analyze the stone.

Do you think this stone is a good buy at $12,300?

Thank you for sharing your knowledge.

What would be a right price for a stone like this? I do agree that it will out perform most stones.

Aren't those reflections of the starfacets?

That’s a tough one to answer. 1.60-1.65/VS2/G/GIA/xxx/none has about 90 stones in the database here. That one is cheaper than about 90% of them and many thousands cheaper than the top of the pile. You ARE trading things off as you move down this list but they may be things you will cheerfully trade for the price. Whether or not that’s the best deal is up to you. I’m sure it’s lovely and it’s priced competitively. It’s not what the premium cut snobs of the world are looking for, but it’s thousands of dollars cheaper too. EVERYBODY is looking for that. This will sell, and I bet it will sell soon, because what you’ve listed are some very popular specs. Whoever buys it will almost certainly be happy.
