diamonds

Mum and I spent the evening looking at pretty diamond rings on all sorts of websites. This all spawned from her story about dad wanting to buy her a diamond ring for their 30th anniversary (which made me go "awwwwwwwwwwwww!"), and in trying to describe the ring she really liked to me, we started trying to find examples on the internet. And, after perusing and weighing all of my options, I have come to this conclusion:

I want a ring with:
-a square cut Canadian diamond (they're just prettier and with more life and nicer cut in general)
-clarity rating of of SI (or better)
-color rating of H (or better)
-white gold
-0.5 Karats would be nice (but I would gladly take a smaller size for a better clarity and colour)

How utterly ridiculous is it to think about things like this? There are so many reasons why this is a bad idea to think about. For one, what happens if a ring that does NOT match that description is presented to me? Am I just setting myself up for disaster? Not to mention the supersticious aspect! Oh lord, the superstitions! Have I totally jinxed myself by looking at all those rings and deciding what I like?
Ok, now things are just getting ridiculous. If I were given a ring that does NOT match that description, well, that's fine. I am not setting myself up for disaster, and there is nothing wrong with looking at pretty sparkly things, the only bad luck comes from wearing a ring on your (wedding)ring finger before you are married/engaged. And it's not as if I've gone ahead and planned a bloody wedding, I'm just looking at pretty sparkly things and deciding what I do and do not like, much like watching a fashion show; just because I really like one of the outfits on one of the models does not mean I will be going out and buying it, I may however make note for future consideration in wardrobe planning.
So there, I don't seem the least bit neurotic, do I? Good, it's settled then.
