The only thing I can see against it is the Fluorescence which, having looked in various newsgroups, most people are not worried about up to moderate.

Could anyone who has seen moderate Fluorescence comment on this?

If the diamond doesn't look oily under the sunlight, fluorescence shouldn't bother you.

Proportions for this diamond really looks much better. This stone should look larger for its weight.

I will have to get the diamond shipped to the UK before I can check it out.

If it is GIA or AGS, you can be pretty sure the fluorescence is accurately graded.

Moderate should not take away from the stone and may even make the H color look whiter.

If fluorescence is too strong, the diamond can look milky or oily, especially in sunlight.

You need to clarify that the fluorescence is blue. Fluorescence can also be yellow, orange, green, etc. which is considered to be undesirable in a colorless diamond.

You need to buy a diamond with a fair return policy and have it checked by an independent appraiser who can make sure that the c's on your report are correct and who can also test the fluorescence. Some labs are not as strict in their grading as GIA and AGS.

You'll also want to know that the inclusions in your diamond are not eye visible if this is of concern to you and that they are not any that can affect the durability of the stone.

You can save money and possibly find an even better cut diamond by staying under the 1.0 carat mark. Cutters will slack off on the cut quality in order to hide weight so they can charge more, as the price for a 1.0 carat diamond is greater than the price of a .99 carat diamond, with all the other C's being equal.

Edit - I see you're buying in the US. You can have your diamond appraised by Dave Atlas, www.gemappraisers.com, before paying for shipping to the UK and worrying about having to return it in time for a return policy expiration date. In fact, some dealers will send a diamond to Dave before you even pay for it. Then if you decide you want to keep it after Dave examines it, you pay for the diamond and have it sent to you.

Rockdoc is another good appraiser, www.consumersgemlab.com who has the same policy, but I think he is away just now.

BTW, EGL (some franchises may be more consistent than others) is described by many experts on other forums as notoriously overgrading color, clarity and fluorescence.

Many thanks for your comments.

The diamond is coming from Diamonds-usa. I have a chat with David Braverman who was very helpfull.

He even offered to take the diamond out of the vault and look at it for me.

He said the Inclusions (2 of them) are both on the girdle. He said it was a very nice diamond.

The return policy is 14 days money back.
