Hi All,
Thanks for the very informative posts here on the forum! I have learned already quite a lot, but I'm still in doubt about what diamond to buy for the engagement ring....
On one hand I like everything in "good" or "very good" quality in my life and I usually buy products in the mid to mid-high end of the market. This goes about almost everything from clothes to food to electronics
On the other hand I'm also still Dutch and I don't like to pay too much 
I'm looking for a classic 6 prong "Tiffany" style solitaire in platinum 950. My girlfriend has US size 5,5 (16mm) and she likes the thin rings (2 mm). Similar to the ring below.
I noticed that some stores have "shiny" rings in platinum and others have "matte" or "frosted", I tried to find out what determines this, but couldn't really find an answer (probably due to English not being my native language and I was using the wrong search terms?).
I'm doubting about what kind of diamond to put. It will be a round/brilliant shape for sure
Since I'll be going for platinum, the color should be a "white" as possible from what I understood?
On one hand I tend to go for a smaller 0.64-0.66 D/E IF ex/ex/ex one with GIA certificate, on the other hand I would prefer to have a 1ct one as well, but that would be outside of my budget in similar quality of course, but I would be able to find a decent one in a lower color grade like G-I and with some more "flaws" like VS1/2 or SI1.
Seeing that she has a quite small US 5,5 size and would like a thin 2mm ring, I'm a bit worried that a "bigger" stone might not look very proportionate (though the difference between 0.65ct and 1ct is only 0.9mm so the difference is hardly noticeable) ?
It's my first time buying an engagement ring, so I am a real rookie, sorry
I plan to spend somewhere between EUR 4.000,- and EUR 5.000,- including the ring.
Thanks for all your advice!
