@redneckincanada: Okay, first of all, as I see this is your first post, welcome to the Hive! 🙂
You can read about the 4Cs online, just google it, there are lots of places that explain them in great detail, I really like this one: http://www.goodoldgold.com/4Cs/
But when choosing an e-ring, you really should consider your girl’s taste first. She likes rose gold, that’s great to know. Do you also happen to know whether she likes complicated, elaborate jewellery or simple solitaires? What’s more her style, something like this:
Or something a little more like this:
Something else you need to consider is what shape of a diamond she’s attracted to. Round brilliants are classic but there are also fancy shapes some women prefer, such as priness cut, oval, asscher, marquis…
Does she wear jewellery at all? Not necessarily fine jewellery, look at her costume stuff if she has any. That would be a great way to know her style.
Do you have a good relationship with her mother, sister, best friend, cousin maybe? Ask them! She might have mentioned something to them, like a favourite shape or style.
That’s of course if you want to keep your proposal a complete surprise. You can also flat out ask her what she likes, or maybe show her some pictures or go to a jewellery shop together. She may also surprise you by not wanting a diamond. Your budget is more than enough for a very nice diamond ring but if she’d prefer a really big rock of any kind over a smaller diamond, you may also look into moissanite or maybe morganite – they’re gorgeous with rose gold! Some Bees have them, look around. Another thing to consider is how big or small her hands and fingers are. If your girl has small hands with thin fingers, a huge rock in an elaborate setting might look silly or out of place.
Now the safest way to go, if you want your proposal to be a complete, out of the blue surprise, is to buy her a round brilliant solitaire. You know, like the Tiffany commercial. Of course you know she likes rose gold so get her a rose gold solitaire. If she later decides she wants a more elaborate setting, you can have her ring reset at a later time – it’s a great anniversary present!
Since you wanted some places to look online, I suggest you go to ones where you can really see the diamonds and what they look like.
http://www.bluenile.com/ (only signature cut diamonds have pictures!)
I hope that helps! I think all of these sites include really good diamond education too if you want to do some more reading on the 4Cs.
And of course you can always come here and ask, I’d be delighted to help, and I’m sure the other ladies will too.
Good luck and congratulations 🙂
