I love it for 4 reasons in this order:
1. Gives it that lovely blue-ish lavender tint under sunlight
2. Makes a lower coloured stone a touch whiter
3. A bit less in cost (only in higher coloured stones)
4. Fun fluoro to play with under UV lights

On high colours especially..., with the correct amount of fluo. (strong to very strong (no yellow))..., it would give a type of crispiness to the transparency of the Diamond!
In my personal opinion..., it is surely worth a premium! So as long as the Diamond market discounts those..., take advantage...

I can''t wait till I get to play with it IRL and see the effect

I had a stone with med. blue for 30 years and had no idea it even had floro until I had a jeweler look at it one day when I was considering setting it in a 3 stone setting and he told me it had it! So let''s just say it had no visible effct on the stone as far as I could tell! I would be fine with getting another one if it discounted the price of the stone!

My D-color e-ring stone has med blue fluor, and I LOVE it. Though I had only seen the effect in photos at the time, I asked my FI to do his best to get a stone with at least med fluor. The lavender color is lovely in the sun, and I find it gives it an amazing look of transparency/depth. It''s like the blue light lets you see all the way into the depth of the stone despite all the white/refracted light reflecting back at you. I went to a haunted house this past Halloween that had lots of black lights, and the effect of my glowing diamond was just plain fun.

How exciting! I didn''t know the fluor has so many appealing affects - my new stone will have med fluor and I admit this was one of the factors that helped me decide - now I can''t wait to see how it looks IRL!

Yes. i took a diamond with strong blue FL out into direct sunlight for a customer to tell them if the blue was very obvious and it was. I thought it looked awesome and i bet it would look even cooler under black lights.

I don''t see how yellow flourescence could ever be a good thing? Why would you want the possibility of yellow tint added to the stone''s true color? Unless it was already a fancy yellow and that could be interesting.

Having yellow flouresence is a GOOD thing in a fancy yellow coloured diamond, BAD in a white/colourless diamond.
Usually, when it is stated as faint, medium, or strong on a cert, it usually means blue flouro but it''s always good to double check that in a colourless diamond. It is very rare for strong fluoro to have a negative effect but it does happen. Sometimes the stone might appear milky or oily but you need to see the stone and judge this.
I agree. Personally, I'd pay more for fluorescence. Why? Because I think its cool and because it lends additional interest. That it usually results in a discount in DEF stones (~10% in a D to ~3% in an F, if I recall the chart I've seen correctly) is a super bonus in my opinion.Date: 5/9/2008 7:58:54 AM

ETA: My wife's F color EC has med blue and I chose that diamond over others because of the fluorescence.

I like flourescence. I like it if it is faint to medium blue because I think it is cool in the sunlight. You see a tint of the blue, or at least I think I do. I don''t know about yellow as I have never seen it yet. I don''t think I would buy a strong flour. stone only because I heard that it is milky sometimes. I don''t know from personal experience if this is true, just from what I have read.

Mostly myth. Very few stones (even with strong flour.) exhibit milky or oily effects. It''s actually a fairly rare occurrence. That said, all you would have to do is take the stone out in the sunlight and have a look yourself, or ask the vendor to give you their opinion.

I am working on an answer to that - it is rather complex, but really stoopid.
Most of the reasons I have discovered make no sense at all.
I hope to publish something in the journal section in a few months.
By preference my store would be full of fluoro diamonds.
Also I am OK with some diamonds that look oily in direct sunlight as long as they do not in cloudy or shaded daylight.

Now I''m interested in this topic because the side diamonds in my ring look very different to me, and an appraiser said they are about the same color & cut etc., but he did notice that one diamond on each side had very strong blue fluorescence, which he thought might account for the difference. Does this seem likely? Can 2 similar diamonds look very different due to this only? (They are 12 points & 16 points - on one side it was the 12 point diamond that had it, and on the other side it was the 16pt one that had it. )

I was just going to make my own comment about why I love fluorescence, but this was so well stated that I had to quote it first.
As I said to a client yesterday in Detroit, I am in Boise, "Fluorescence is an extra gift of beauty the God puts in some stones. Out of doors they show this faintest hint of glowing blue that just looks somehow magical.
When I got into the business I paid a premium for these gems from my suppliers and proudly passed it on to my clients who loved the gems with that extra touch of beauty. When the investment craze hit in the late 70''s, people who were selling ladies shoes the week before were now selling diamonds from boiler room phone banks and had no clue what fluorescence was or how to explain it and it came to be viewed as a bad thing.

Note: I am well aware that somewhere below 1% of medium to strong fluorescent stones are what are called "overblues" and will appear oily. My comments above do not apply to these rare stones. I use the word stones intentionally, as these are not gems.
