Sorry for the delay - went to get some photos to post up and then spent 4 hours sorting out Photobucket!!! Doh!
Okey dokey, here goes ............
Look at this diamond (note to self - use handcream!). Where do you think it sits on the D-Z colour scale? As a reminder DEF is colourless, GH is near colourless and while IJ is classified the same, you're getting nearer to the diamond showing some warmth and having a vanilla tint. KLM will show some yellow etc etc.
Scroll down for answer! Are you right?
Ok, it's an I in colour. Typically an I would not be looking this white and if I put this diamond next to an E or F colour, you can't tell the two apart.
This is because this diamond has been graded by the GIA as having "Strong Fluorescence". Fluorescence (i.e. how the diamond reacts to UV light) is typically blue, although other colours are known but what this means is that the blue of the fluorescence negates any yellow in the diamond making it appear "blue white" - now look at the first picture again and you'll notice the blue coming through. Years ago, blue white diamonds were a premium but their popularity waned. They're coming back in fashion and are a very good way of buying a cheaper diamond but getting a super white look!
This is the same diamond under UV light - isn't it cool!!!!!
Just a word of warning ...... if you have a diamond that has
intense fluorescence, the diamond can have a milky or oily look to it and won't be desirable.
So, why don't you test your diamonds - you'll be surprised at how many of your accent diamonds might actually fluoresce! You can buy a torch on Ebay to do this very cheaply
http://cgi.ebay.co.uk/15-LED-UV-LAS...39:1|66:2|65:12|240:1318&_trksid=p3286.c0.m14 Just type LED Torch into the search bar in Ebay and you'll get a number of choices.
Or you could pop down your local nightclub and stand under a UV light!
Here's another picture and you can see some of the diamonds have fluorescence and some don't ......
Have fun!
