I bought a diamond online from Bluenile but its not sparkling at all. Its a 0.55ct F VS1. On the GIA certificate, it has cut (excellent), polish (excellent), symmetry (excellent).
I don't know why but the diamond looks quite dark and have no shine. It's already the 3rd best color (F) but it doesnt look white for some reason. Theres not much sparkles... when I move the diamond around to try to see those reflection, its looks very bland.. like alot of dark spots and no color.. is this normal?
I think you haven't done enough homework. Luckily there's a 30days return policy. I'm kinda wondering, with a 30days return policy like this, how many returns are there due to unsuccessful proposals
For those who doesn't mind the brand and wants a performing rock and wants to venture into online hassle free purchase, able to return the ring if proposal is unsuccessful
, and no weeks of waiting, try having the following filter -CUT : Sig Ideal
Colour: G - D
Clarity: vs1 - IF
Polish : EX/ID
Symmetry: EX/ID
Fluorescence: none
Depth: 59 - 61.8
Table : 53 - 57.5
L/W ratio : 1-1
then filter out base on the carat size or your budget, from there, take a look at the GIA certificate and look out for rocks with the following:
Crown angle: 34.3 - 34.9
Pavilion angle: 40.6 - 40.9
Because rock of <1carat weight will not have their inclusions plotted on GIA cert, Weed out any rock that has "crystal" & "internal graining" to play safe
After that, go thru the GCAL cert of those shortlisted rocks. There's a photomicrograph of the rock that'll allow you to see if the cuts are proportional or if there's any facets that appear out of place
then to be sure, check out it's HCA here
I came across this write up talking abt the 3 different range HCA will tell you - TIC, BIC & FIC (guess it's just on the type of performance)
