NOMG - one of the complaints with Blue Nile is that they don't give out enough information on their diamonds to be able to make an informed choice about whether the particular stone you are interested in is a good performer. Also within their top cut Signature Ideal diamonds, the quality of the cut can vary considerably.
When it comes to fluorescence one of the drawbacks of it is that it sometimes makes a diamond appear hazy or milky. Some companies such as Brian Gavin Diamonds sell fluorecescent diamonds but theirs are properly screened to make sure their fluorescent diamonds don't have negative characteristics. The advantage of a fluorescent diamond is that it can have the effect of making the diamond appear whiter than a diamond of the same colour grade without fluorescence. Most of the time your diamond will fluorescence will appear like any other diamond but can turn a blue/purplish colour in bright sunlight. Kinda cool!
Again I would recommend Pricescope if you are in the market for an engagement ring in order to get a diamond that is a great performer. There are people there with a vast experience with diamonds and the advice they give is free. Again though with advice don't compromise on colour or clarity over size if this isn't your preference. Look at different coloured diamonds in jewelery shops to get an idea of your tolerance level. Some people wouldn't go lower than a G in colour, others would love to rock a J and be pleased with the extra size they can get for their money.
