How do I know if the diamond I have is a natural green or not?

As far as I know, while a lot of colored diamonds and colored gems are colored by chemical impurities in the stones (like nitrogen, for example) natural green diamonds are created by structural changes to the to the crystals usually caused by some sort of irradiation. Distinguishing between Mother Nature's irradiation and man's artificial irradiation takes a very skilled gemologist.

Thank you. That's what I been reading. I know the pictures are the greatest either. I been Reading that if it's colored by man it's usually distributed evenly and natural colored diamonds will not be evenly distributed. Is this true if you know? Also in the pictures please take note there is a white spot. This spot is clear and white like a white diamond and is not a Crystal or feather etc. What might cause it to be almost I could say a very nice clear white and green diamond mix, although that wont happen to my knowledge.

Irritated meaning enhanced/colored by man?


May I ask you for a value (guesstimate) on it?
It's 1.76 ct Also does the white spot (not cracked or feathered) decrease it's value? Does that spot turn it to an I1 and how do you grade the color?
Also can I have the green removed or should I leave it? Value speaking I mean....

Thank you in advance for your help....

Hi Sherry!
Irradiated means treated by man- it's a non reversible process that bombards the diamond with radiation changing the color.
Natural green diamonds are the color they are due to million year old natural radiation- which I believe Trinkette referred to- but they are not the same color like man made irradiation, as yours seems to be.

I can't see the spot- nor accurately grade the clarity from a photo anyway....did you just buy this diamond?
If you'd like to post the price I'd be able to make a comment.....

PS- what collage?? ( sorry if I don't remember, but hopefully you'll refresh my memory...)

Welcome here!

If you are using a digital point and shoot camera, try putting the ring in bright light on top of a book or something.  Get the right height so that you can just rest your camera on the table or counter and still zoom in.  Zoom in a ton and see what you get.  Since my macro lens broke, I found my P&S digital camera does quite well. 

I hope all that made sense if not feel free to ask.

I do see the white spot, but obviously couldn't even begin to guess what it is.

Hi everyone     Thank you for all your help... David I made you a colloge of your diamonds it was a long time ago though I am not sure how else to help you remember but that's OK.
I only paid 250 at a pawn shop, I had been keeping my eye on it for about a year and a half until they dropped the price, however the other day when I went in I was not expecting it to go that low... They started it out at 3500 then it just keep dropping in the price the longer no one bought it...

I will try the light with the camera set on the flower setting thank for your that help as well...
You are all awesum!!!!

Oh I know the carat size cause I had my ring band sized and he (jeweler) messured the stone with his mm gauge, He is good at making silver jewelry and sizing rings he has a gauge and the book but I don't believe he is a full time jeweler because he didn't know what the clarity or color was either.

Hi Sparkly can this be fixed?? The coating you mentioned above with your diamond.

Thank you all for your help. I ended up trading the green one in for a beautiful 1.40tcw (.65 VS2 Color F center with 26- .03ct little diaomnds on the sides) I love it.....I will work on a better picture of it but here is the one I have for now.. What do you think??

you were able to switch the green ring for this for the same price??  you GO GIRL!  it is definitely a much safer bet in terms of value, and if you love it, all the better!

Nice catch!
