Newly bought diamond e ring query

[Just_Starting]

Hi this is my first post so apologies in advance for any mistakes. I have a limited knowledge of diamonds and would therefore like your opinions on this one that I've just bought. Specifically I am wondering what your thoughts are regarding the 'cut' factor. I am wondering if it is possible that the cut factor has been reviewed perhaps a bit harsh since the polish grade is only good, the symmetry and cut cannot be graded higher than very good (GIA).

So, here is the specification:

Round Brilliant
Measurements:
5.13 - 5.14 x 3.11 mm
Carat Weight
0.50 carat (didn't want this any bigger)
Color Grade
D (perhaps F would have been a better match, but this does look very nice)
Clarity Grade
SI2 (seems eye clean to me, looked very carefully at it, I assume if it were bigger it wouldn't be).
Cut Grade
Very Good (really wanted an excellent cut, however they didn't seem to have the exact specification I wanted and the diamond sparkles so much!)

Proportions:
Depth
60.5%
Table
58%
Crown Angle
35.0°
Crown Height
14.5%
Pavilion Angle
40.8°
Pavilion Depth
43.0%
Star Length
55%
Lower Half
80%
Girdle
Extremely Thin to Medium, Faceted, 3.0%
Cutlet
None

Finish:
Polish
Good (again, I believe at this carat size makes no difference, especially being SI2 anyway)
Symmetry
Very Good

Fluorescence
None

Clarity Characteristics
Feather, Crystal, Cavity

It also has an inscription on the diamond. Please correct any of my observations if incorrect and provide your input, I would be very thankful as I find the information very interesting.

Since I have only had the ring for 3 days I am guessing I could probably exchange the diamond if I wanted to, thoughts on that too would be great.

Finally, just to make it clear - any general observations on the ring would be very welcome!

Thanks for any help.

HCA score is 1.6 VG/Ex/Ex/VG

The grade setting inclusion is a feather. The polish, per that article, adversely affects light return. You are looking at the diamond, clean, not in everyday use. Location of that feather could be a durability problem.

Thanks a lot for the reply, very useful. So, by a durability issue you mean that I may need to clean the diamond regularly? If this can be done at home e.g. with warm soapy water and a very soft brush that is not an issue for me, however if it needs doing professionally that would be tedious!

Regarding the HCA score, could you give me an example of what a typical excellent cut grade would score to give me an indication of the variance?

Thanks again.

Edit:

Just seen that 0-2 is excellent on the HCA scale, so forget that part! .

A durability issue is one when an inclusion such as a feather, depending on where it is located, renders the diamond prone to cracking if it sustains stresses such as being hit very hard against another object. You don't want to have this problem!

Ah that makes sense. Hm hard to say whether or not I should exchange the diamond then. The location of the feather is not specific and I have not seen it myself (only looked through x10 mag and not in great depth). I think it is unlikely the diamond will be hit hard, I suppose this is best to discuss with my partner.

Thanks again for the reply, anymore input on this diamond is very welcome.

A bit of extra information, the diamond cost £1150 by itself, paid extra for it to be mounted. I don't know if that was a good deal or not.

Just researched girdle width, seems that since this one ranges between extremely thin and medium faceted it should not have been used for a ring, especially one where the girdle is exposed. Anyone had any experience with diamonds with extremely thin girdles/think this is likely to be an issue? My partner is careful but a nudge every now and then is inevitable.

Thanks again for any help, learning a lot today!
