Is this a Flaw in Cut or Clarity or Both?

[elysiansfield]

I am new to this forum and have very little expertise when it comes to diamonds. I have found a diamond that meets all the specifications I am looking for that is within my budget but in certain lighting (usually dim light) there is a noticeable round, very white reflection near the center of the diamond similar to the first and second picture of the round solitaires posted here: https://www.pricescope.com/community/threads/band-taking-away-from-1-5-delicate-solitaire.121409/page-2. Is this the result of the reflection of an inclusion (diamond is graded VS2 with pinpoint near the center) or the result of a non-pointed cutlet (even though report says cutlet is negligible) or some other flaw in the ring? Any insight is greatly appreciated.

This is seen face up I take it? I see what you mean looking at the photos, it could be something to do with the proportions rather than an inclusion. Can you post all the details of the proportions of the diamond please, then we can get a better idea, we need the...

carat weight -

Type of lab report and cut grade if applicable
depth%
table%
crown and pavilion angles
girdle thickness
polish and symmetry grades
diameter in mm
star and lower girdle facet percentages if you have them

Have you already bought this diamond?

 

[elysiansfield]

I double-checked the clarity on the report, it actually is VS1. Other info I obtained:

carat weight: 1.272
Type of lab report: AGS
Cut grade: Ideal
depth%: 43
table%: 14.8
crown angles: 34.3
pavilion angles: 40.7
girdle thickness: .8% to 3.7%, faceted
polish and symmetry grades: Ideal
diameter in mm: 7.07-7.11
star and lower girdle facet percentages if you have them: 53 and 79

I have placed a substantial deposit on the ring. I did not notice this "flaw" in the diamond until i saw it placed in a setting and viewed the diamond from an arm's distance. I otherwise love this diamond/ring but am worried I just don't know if the quality of the diamond actually matches the specs.

Thanks!

Thanks!

Can you check the depth and table measurements please? Those don''t look right....

Oops sorry, reading the report incorrectly:

depth % is 43
table % is 56.5

From your description and the pictures, I wonder if you are seeing the small circle where the lower girdle facets end and the pavillion mains converge. This area reflects light a little differently. It can be seen many times in ASET images as a green circle because the light return is different. I attached an ASET "borrowed" from Whiteflash that shows this.

Table looks right, now. The depth you list is probably the pavillion depth--overall depth should be in a 60-62% range. It will be in the center of the diamond diagram on the report.

Jet could be right about what you are seeing, also the table % looks better, if you could recheck the depth please.

Nope. I plan to return it, just as soon as I have access to their server!

Just ''cause I borrowed it w/out permission doesn''t matter, does it?

Oh ok!

dun fink it matters....i fink they would forgive you

Thinking it could be due to the contrast of the arrow shafts. Do you notice this more with the diamond at a distance or arms length rather than when you are observing it close up? If so that is because when your head isn't blocking the light to the arrows, the areas in between light up and ' pop out.'

 

[elysiansfield]

Man, can you tell I really am a newbie in reading diamond grading reports?

Jet, you are correct, I stated the pavilion depth, not the overall depth which is 59.8%

I was told by the jewelry that this is the reflection of that green circle you mentioned, Jet. But I find it odd that it is not dead-center and to me it looks like an off-centered "hole". I wasn''t certain if he was pulling my leg so I did some research and came across this forum. I found only the two photos I linked to that had this. Wouldn''t all photographed diamonds show this?

Yes, it was more noticeable when the diamond was held at a distance. Isn''t this how the diamond would look to someone else standing from a distance? It would like a round mirror within the diamond. Not attractive in my opinion, but maybe I just don''t know how a quality diamond is supposed to perform.

Only when the angle of the photograph is just right (or wrong, depending on how you look at it.

) The reason it is not dead center is that from many angles you only see the reflection coming back from about 1/2 of the pavillion main facets. If you look directly down through the table of the diamond, it should be centered, any small angle deviation may cause some of those facets to reflect light to somewhere other than your eyes, thus causing the off center appearance. Whether the light is reflected to your eyes or elsewhere can also depend on focal distance, you may not see it close up, but yet be able to see it at arm's length, and a person five feet away may not notice at all.

It is a beautifully cut diamond, but only you can decide if it is the right one for you.

That makes sense. I''ll be sure to hold the ring at a right distance and angle so I can be in love with the diamond every time! Haha.

Thanks so much for your responses Jet! (And yours too Lorelei!)

You are very welcome. Best of luck with your diamond purchase.
