Hello.
I am a new member of "colored diamond", I need help about a little but very nice blood red diamond.
I am negotiating the price with another diamond collector in Buenos Aires.
Have you any idea about the price of a blood red diamond?
This gem is not from Argyle, this diamond is from South Africa and is more blood red than Argyle diamonds, it is a round cut red diamond, its weight is 1/3 of a carat and its measures are about 4.2 x 3.0 mm.
Many thanks!

Hello.
Many thanks for your reply!!!
I am close to sure this color is impossible to get using any enhancing method, otherwise we see diamonds with this color every day, and I never seen anyone.
The diamond was tested in a serious gem laboratory, in an official bank in Buenos Aires and the experts opinion is that this diamond was not treated in any way.


  Daniel.

My question is: If the GIA Report confirms that this diamond was not treated in any way, whats about the price of this gem?

I agree with David - there's no point in speculating. As far as anyone (including you!) is concerned, without an authoritative statement to the contrary, it's a piece of red glass.

By the way - as far as color origin, GIA can state "Natural", "[artificial - usually with description]" or "Undetermined". Undetermined does not mean they don't have a view; it means they cannot come down conclusively with a proof of treatment, but the suspicion is strong. All the more so with unusual and rare colours.

That's a great answer David. Put so clearly.

Hello, many thanks for all your comments.
About the question of David "Who knows if it's even a diamond?", I think is is offensive, you don't know me, my name is Daniel Tadey, I am a recognized chemist in polymer science, a researcher from the Buenos Aires University, and the most important, an honest man, the diamond was tested by Profesor. J. C. Fuentes, not a GIA graduate, a geology doctor and Professor of Gemology in the Buenos Aires University.
But, if you want, David, the pictured thing may be glass, but a rare type of glass because its hardness is 10.0 and its R.I. 2.42.
All the best!

As I read the series of posts here, a few thoughts come to mind:

First, Daniel, you sound a bit hurt. Really, I don't think anyone has meant to insult you, quite the contrary, actually. As an educated person, I am sure that you know the rarity of red diamonds. That being said, the chance that someone who is not in the diamond business would come across a faceted red diamond that has NOT been graded by GIA (or perhaps, one of a very few other noteworthy grading institutions), is VERY slight. Naturally, people here would approach such a thing with caution.

And, of course, someone could simply flash a photo of a red stone here and hope that someone less educated might try to purchase it privately. As it stands, people here have taken your post at face value, as an honest inquiry, and have, in my opinion, been quite sensible in responding.

Also, as you wrote yourself, Daniel, David and the rest of the posters here, do not know you (or the circumstances whereby you have come upon this stone). I believe the responses you've received here are responsibly conservative. By warning you to proceed with caution, people here are looking out for YOU. That is a good thing.

Moreover, please consider that the price of a diamond, ANY diamond – red, yellow, colorless, whatever color – is always fluctuating, always negotiable, and from what I know, quite complicated. There are many, MANY factors involved when pricing and negotiating for gemstones and diamonds. Is it NATURAL? What is the clarity of the stone? Quality of cut? Are there surface blemishes? Is the polish poor... good... excellent? Is the stone crystalline? Is the color even? Is it brilliant? Is there fluorescence? Does it flash all the colors of the spectrum? Or, is it a dud, performance wise? THEN, there are factors like who is purchasing the diamond? Is it someone you know? Is is a wholesaler? Retailer? Private collector? A purchaser's credit, past history in the diamond market, financing plans, all come into play. In the end, all these things matter, and combined, these elements can make a BIG difference in price. Then, when you add that a potentially extremely rare color – red – suggesting that a fair assessment for price could be had online, to me, seems completely impossible.

Now, if I were you, and I had access to such a gem, and I wanted to know an approximate worth, I would first send it to GIA to get the necessary info so that you know EXACTLY what you have and can prove it to someone who may be interested. Meanwhile, while I wait for GIA results, I would study recent auction results (Sotheby's, Christies) to seek out similar stones (if there are any) and research colored stone vendors online to find other similar stones that are already in stock and for sale. THEN, when my diamond report returns, report in hand, I would start contacting reliable colored diamond vendors, or an appraiser experienced with such stones, to discuss pricing parameters. If what you have is truly a rare, natural, red diamond, then, your research would be totally worth your time and money spent.

I'm sorry, but, to me at least, there is no easy answer here. And, if someone were to give you an online pricing answer based on the facts you have presented to date, I would be less than impressed with his/her professionalism.

Daniel, please, do find out more about the stone. As I wrote, if it is all you think it to be, then, the diamond should be documented. Finally, I hope that it is all you expect it to be, and more. And, I will be most interested to hear how this turns out. Meanwhile, do feel welcome here. I look forward to hearing more from you.

Hi Daniel.  I hope you do check back in with us and catch up on the latest responses.  

I'm not going to belabor anything said before by forum members or David - they all know a great deal more about diamonds than I, and from your posted credentials, so do you.  But whether you are as knowledgeable in the business as David or OMC, or a dilettante who loves the beauties she can't afford, like myself; this is still an excellent forum for honest answers.  OK, sometimes a little less than tactful, but honest and well meant.

For what it's worth (and being free of cost, not much), I have to admit to never having seen a diamond of that color and saturation on any website even for display, let alone for sale.  Never come close to seeing such a thing IRL, and the Smithsonian's hall of Gems and Minerals was my favorite place to visit every weekend for 15 years.  Maybe others have seen something close, but please understand our caution.  Nobody here wants to see another make a questionable decision when there is information available.

Please forgive us for any offense given.  We didn't mean to insult - just point out how little information was available for us to work with.
 
So.....can we have some more pictures please?  Like bottom up on a white paper background, maybe a shot under UV to see if it has any fluorescence?  And if you do get a GIA report on it, would you please share it?  This is truly a unique and rare stone, given what you have shared about it most recently.  I know you've piqued a great deal more interest than just mine.  

And keep in mind, we are always as ready to celebrate a wonderful acquisition  
as concerns   for the validity of the background information available on the same.  

Hello.
If anyone says "Who knows if it's even a diamond?", it or say "The member is a liar" is the same.
From any member it may be accepted, but from the moderator??? From the page owner??? This stupid has not any education.

The diamond experts know that the ruby red color in diamonds, can not be get in any way.
Bye.

WHEN I SAID "THIS IS AN OFFENSE", I ONLY SAID ABOUT THE PHRASE:


              "WHO KNOWS IF IT'S EVEN A DIAMOND?"



NO TO ANOTHER COMMENTS.

Hello Trinkette .
Please check it, the page owner said:


        "WHO KNOWS IF IT'S EVEN A DIAMOND?"



 

Here there are only offensive comments, I will not post never more.


  Bye.

Sorry, I must add that after attacking people here, then, adding a link to one's own site is most inappropriate, and I am sure, quite offensive to many people. Very regrettable.
