I've been reading a lot of the posts on this site, and have found the information incredibly helpful. Unfortunately, I came across the site only after putting down a $1,000 deposit today on a stone for an engagement ring today. I visited a handful of jewelry stores over the past few months, and did a decent amount of research, but admittedly never came to understand proportions. For the most part, I trusted my eye on judging each stones' brilliance, though I made use of several tools I grew comfortable with throughout the process--and did put natural light to use. I wound up going through a wholesaler, which led to my making a quicker decision than I originally anticipated. Only after I got home and started looking over my GIA certificate did I begin digging into all of the #s associated with the stone... So, I'm coming to you all here to find out whether or not I should feel buyer's remorse and, if so, whether I should try to do anything about it (i.e., see if I could switch to a different stone from his reservoir).
The stone I wound up going with was 1.80 carats (Round Brilliant), H color, SI1 clarity, and an excellent (overall) cut (excellent, very good, excellent). The measurements are: 7.74 - 7.78 x 4.88 mm. My concern now after doing more research really stems from the total depth %, but I'll just share all of the proportions and see what you think...
Table size: 57%
Crown height: 16%
Pavilion depth: 43.%
Star length: 50%
Total depth: 62.8%
Crown angle: 36.5
Pavilion angle: 41.0
Girdle thickness: thin - medium (faceted) 3.5%
Lower girdle/half facet length: 80%
Culet: None
I paid $12,824 (pre-tax) for the stone. The stone was eye clean, and its inclusions were faint and along the outside of the table. I'd gone into everything with a budget in mind of $15k and a desire to find a weight somewhere around 1.7-1.8 if possible. I'd seen some really nice diamonds in the 1.65-1.69 range, but ultimately felt the additional size was important. I was happy to come in under budget (should be about $14,200-ish after taxes and adding in the simple setting I'm going with). For those of you with far more experience than I have, do you think I did okay? I'm a bit nervous about the total depth (and also crown + pavilion angles), but of course was being pretty cost conscious throughout this long process. Thanks in advance for your help (fingers crossed).
