Strong Blue Fluorescence

[Zand]

Hi there,

I have been reading this forum for a while and I am a first time poster. I have been looking for an engagement ring for my girlfriend and I was wondering what people here thought of strong blue fluorescence. My girlfriend's birthstone is aquamarine and I have seen a few pictures of diamonds with strong blue fluorescence in UV light that I rather enjoyed the look of because it seems somewhat unique. I have read that this can also make a diamond that is a lower color grade appear brighter, in the experience of people here is this true?

I have been comparing a few diamonds on the HCA and some that show ideal cut on Bluenile aren't scoring very high on the HCA while some that score Very Good are scoring fairly high. I have seen a number of diamonds in person and I understand the cut scoring but I don't really understand the HCA, if HCA is higher on a very good stone than an ideal stone would the very good cut look better?

Final question is in relation to diamond clarity. I was considering buying an internally flawless stone but after reading here it seems that VS2 or higher wouldn't be likely to show flaws face up. The stone size I am looking for is 0.7-0.8; any larger than that and my girlfriend would probably be annoyed that I spent too much money.

Thank you for your help and I appreciate all of the knowledge people on this board possess.

Personally I really like fluor. Not often but sometimes in colorless diamonds it can cause a milky appearance so it's always best to have the stone evaluated, but many people search for stone with fluor because it's a really cool characteristic.

I also agree that VS and SI stones offer the best value. Above a VS1 your paying for clarity that you can't visual appreciate.

If your considering an AGS ideal stone, there is no need to run the proportions through the HCA as the stone has already been evaluated for light performance. The HCA is only a predictive tool, used to help people weed through an enormous online inventory. It shouldn't be used as a selection tool, but rather an elimination tool to help consumers establish a short list of potential stones by predicting it's likely light performance. Once you have found a diamond that scores well you should ask for idealscope images, these will give a more accurate assessment of the diamond potential.

I have a diamond with SBF and I love it! It is something I never see, but I do have a little UV light when I want to have a look at it! It is an amazing natural phenomenon, I think! But, I wouldn't order one blindly. I got mine through Good Old Gold who checked the stone for light performance for me and made sure the SBF didn't have any negative effects. I also will only buy diamonds from vendors who post magnified images of the stones. I always buy VS1 or VS2 diamonds and don't feel that the higher clarity is worth it. VS1, especially, is totally eyeclean and the inclusions are almost impossible to see with a 10x loupe.

Here are some pictures of my diamond with SBF:
