Q:

Hi Liz,

Thank you for putting together this website and being willing to offer advice. I am looking for a diamond for my girlfriend’s engagement ring and I found the following one on James Allen. I was wondering if you could take a look at it, give me your opinion, and let me know if there is any outstanding reasons this might not be the diamond I should purchase.

Hello Derek,

I’m happy to help you. Thank you for your kind words. 😉

I’ve reviewed your diamond from JA and I don’t recommend it! The cut and optical symmetry isn’t ideal.

If you are looking for a F+, .70ct + diamond that is eye-clean then I recommend this gorgeous .71ct D VS1 for $3,470.00: https://enchanteddiamonds.com/diamonds/view/R71-5XMQRU

James Allen .73ct E VS1 ($3,430.00) diamond on the left and Enchanted Diamonds .71ct D VS1 (3,470.00) on the right.

This diamond is gorgeous, has perfect light performance and beautiful optical symmetry. You can easily see this in the image with the dark arrow contrast that is evenly spaced and crisp. It has medium blue florescence but this doesn’t affect the brilliance or the translucence of the stone.

I would highly recommend this diamond for you. Please let me know if you have any questions.

I look forward to hearing from you.

Liz

Q:

Liz,

Thank you for giving your feedback on the diamond we sent you and for recommending another. We really liked the one you suggested, our only concern was the medium fluorescence in a colorless diamond. Do you think we should be concerned about this?

We have continued searching and have found an additional five that we are interested in. We would really appreciate your opinion if you wouldn’t mind taking look.

Hello Derek,

You do not need to be concerned about medium blue fluorescence in a ‘D’ colored diamond. This will have no affect on the transparency or brilliance of the diamond. Strong or often times Very Strong Fluorescence will affect a very few diamonds in such a way that when UV rays are passed through the crystal, it will appear cloudy or milky in appearance.

By the way, did you know that long ago colorless diamonds with blue fluorescence where once highly coveted? They were called ‘Blue White’ diamonds and were even mentioned in Alfred Hitchcock’s famous movie called, “Marnie” (and I’m sure plenty more movies of that era).

Anyway, of the diamonds you selected below, I recommend:

The cut is ideal and diamond is eye-clean. So, if you wanted to get a diamond without fluorescence, this would be my choice for you. Please let me know if you have any questions!

Kind Regards,

Liz
