    Not at all (center diamond), and that was important to me for the crispness, but 2 of my melee do (1 faint and 1 medium fluor.) I’ve got a UV light that shows it well.

    The jeweler told my Fiance that it has a slight blue florescence and showed him when he was buying the ring, but I have never noticed anything  Not around many black lights! It doesn’t show at all under regular lighting.

    @RenoSweeney24:  Mine Does!

    it’s really cool. I go to this club/country line dancing place every week and it looks awesome under the blacklight. Let me see if I can find the picture…..

    Mine does, and that was one of the qualities I wanted in a stone. My mum’s diamond is old enough that it was sold as a blue-white stone, which used to be highly prized until jewelers started abusing the term. All these years she didn’t know what that meant until I showed her with a pocket UV light. Most chain jewelers won’t deal with stones that fluoresce anymore, because it takes too much effort to educate a consumer. Better jewelers will carry all ranges, from no fluorescence to very strong blue. Blue is the most common, although diamonds can fluoresce blue, yellow, green, orange or white. The Hope diamond exhibits red phosphorescence, so it actually continues to glow for a while after being exposed to UV light. VERY cool.


    It is estimated that fluorescence negatively impacts a stone less than 10% of the time, and GIA studies have indicated that it is probably far less than that. GIA trained jewelers were unable to detect which stones contained fluorescence under normal lighting conditions the vast majority of the time – almost all the time, in fact. If GIA appraisers cannot tell when closely examining the stones you can bet that the vast majority of people will never know whether your stone fluoresces or not unless you are under black lights.

    I have no flourensce but have read that it is good if your color of stone is j or lower. It makes it look whiter.

    Whoooaaaa that is way cool! I have a ring I got for a sweet 16 present with three tiny diamonds. I remember being at a night time bowling alley once and one of them was glowing and I always wondered why! I thought perhaps it wasn’t an actual diamond. Nice to know it is! That is so super cool!

    Does having a diamond that has fluorescence make it more or less valuable? Or does it even change the value?

    @taylorkirby:  It makes it about 20% less valuable, because the more it fluoresces the more hazy/milky it gets at the same time (so the stronger the fluoro innthe stone, or the more UV componenet in the lighting situation, the less crisp it will be). It is because fluoresence is due to jiggling atoms. The more they jiggle the more they release light but the more distorted or fuzzy something seems.

    Some people say they personally can’t notice this effect on any but the strongest fluorescing stones, but many others (such as me) notice it and don’t like the fuzziness at much lower amounts (and find the very strong ones to look very oily indeed). It was really important to me that my diamond was extremely “crisp.”

    @joya_aspera:  Ooooh. That makes sense. I picture dancing atoms inside a diamond having a disco haha.

    I’ve never actually sat down and looked at diamonds to compare them so I don’t know if I would be able to tell. My Future Sister-In-Law just got engaged and her diamond looks pretty fuzzy and I couldn’t figure out why but I bet it is because of that! The thought of having a glowing stone is way cool but in reality I mean how often are you around UV lights? Unless you work at a club or something…

    I was showing Fiance pictures of diamonds under UV and he wasn’t as impressed as I was. πŸ™‚
