Red Diamonds: How Many Vivid Pure Red Diamonds Are Known to Exist Today and At What Value?

by 6 Comments

Red diamonds are perhaps the rarest type of gemstone which is currently in existence today.  Very few individuals lay their eyes upon a red diamond which makes its uniqueness even that much more so.  Although colored diamonds in general tend to be highly sought after and due to their rareness not purchased as often as colorless diamonds, the red diamond is the absolute top of the line gemstone.  How Many Vivid Pure Red Diamonds Exist Today? To say that this type of stone is rare is an understatement.  In fact, it is claimed that less than twenty naturally red diamonds are known to exist today.  This is not to say that more will not be uncovered in the future however it is likely that the number will stay around this level for quite a while.  Due to the lack of available vivid pure red diamonds, the price tag which is on each one, if the stone is even for sale, will take one’s breath away.

How Much Does a Gem of This Type Cost?

Stones of this type, should they go up for sale, can cost anywhere in the millions of dollars range.  The largest red diamond ever graded by the Gemological Institute of America is a 5.11-carat stone which eventually sold for around $8 million.  This stone was called the Moussaieff Red as it was purchased for this amount by Moussaieff Jewelers.  Smaller versions of these stones such as ones which are a carat or less could sell these days for $2 million or more.  Considering the rareness factor associated with red diamonds, it is no wonder that these jewels cost a pretty penny to purchase if one is able to do so at all. 

Where are the Red Diamonds Which Are Not For Sale?

Out of the approximately twenty or so red diamonds which exist today, only a small portion of stones are currently up for sale.  As for the ones which are not available to be purchased, some are in the hands of private owners or jewelers whereas others are on display at museums, such as the Smithsonian Museum.  Others have disappeared for one reason or another.  Whether this elusive diamond will pop up in the future remains to be seen by the red diamond following public.

The Beauty of This Gemstone:

There are many attractive factors relative to the red diamond. First, since this gem is so rare in nature, the desirability factor is even more so.  Something which is harder to get is often more coveted by the masses.  Secondly, the vivid pure redness of the stone presents such a picture that it is simply breathtaking.  The aesthetic attributes of the red stone make it extremely desirable for diamond lovers everywhere.  Lastly, the uniqueness factor also answers the question why it is so highly thought of in the gemstone genre.

    I have a hunch that a piece I recently picked up from an estate sale very well might be a red diamond. I took it to my local jeweler and wasn’t impressed with his evaluation. He preformed no testing, he just told me I had a natural gemstone. He said in his opinion I had a mozambique garnet, but my stone looks nothing like this type of stone. It has a vivid red color and has faceting like I have never seen before in a gem. I think it is a heirloom piece and has been passed down some years. The ring is filled 14 ct yellow gold and is bezel set. Im having a hard time identifing this stone. any suggestions?

    And I have found a orange diamond, and was wondering if you thought a stone like that would be worth investing in? It would cost $2,500 for me to buy it, but the seller claims it has a value of atleast double? Where do you see the market for this colored diamond going? I know they are very rare and this is the first chance I have had to even buy one. It is more than a ct in size and is in a heavy 14 ct wht gold setting.

    Thanks for your time.

  3. Hi Michael,

    If you let me know what City and State that you live in I can recommend a gemologist that is close to you that will be able to tell you exactly what you have.

    As far as buying the orange diamond that you are speaking of I think you answered your own question.

    Why would someone sell you something for $2500.00 that is worth at least $5000.00? If it sounds too good to be true it probably is.



  4. I live in Maryville, MO, and I would greatly appreciate it.

    Thanks for your opinion on the orange diamond as well.
