There are lots of ways to lose money when investing in diamonds. A knowledgeable diamond buyer bought a 4ct for $16,000 and figured his fortune was made. He eventually took it to the NYC diamond district, only to find store after store with display windows with similar stones looking like gravel. He ended up getting aroung $12,000 for his rock.
Diamonds are coal with a great press agent. D color has been the standard for decades, but that didn't stop them from promoting "champagne" diamonds when somone found a mountainside of crappy colored stones. The latest are "chocolate" diamonds, which is nothing more than an even crappier color stone.

Hey Junior, I as well am sorry to hear about your mothers passing. To answer your question with what information I have...
I have a new client I am working with who specializes in Diamond Investing. The type of diamonds they focus on for investment purposes are fancy colored ones such as pink, yellow and blue.
I would think that these are the most rare, hence why they are good as an investments.
You can learn more by checking out the site here: *** Link removed by the Staff ***
I wish you the best!

A customer who claims pretty comprehensive diamond knowledge told me last week that the per-carat record was a lower grade .98 red @ $1.2 million a carat.
Evidence to the contrary welcome.

 Deep red diamonds fetch prices higher than deep blue diamonds. But natural red diamonds are so extremely rare that they're mostly unavailable, like 1804 US dollars.

Gave a diamond studded necklace for my wife for the birth of our firstborn. 1st thing she asked "how big are the diamonds?" I said "all the weight is in the white gold." She said "good boy."
Though the diamonds = coal argument don't really get to me (the leaking bag of meat and bones that's my son is just as cute, gold and silver are just 2 elements on a table), i'd still pass on it. Diamonds is one of those things i'd need a degree to understand what I'm buying and would need to market till no tomorrow or teach just as much knowledge to the buyer to sell.

If you are going to invest in diamonds, like anything else, you have to know what you are doing.
I suspect that most of us in the CCF know something about coins, but very few us us would be savvy enough to invest in diamonds, and know what they are doing.
I am a gemcutter. I facet sapphires.
I have a couple of diamonds, both cut and uncut. However, I DO NOT know enough to be able to invest in diamonds in a knowledgeable way. That does not stop me from owning them. They are an integral part of my gem species collection. I have about 200 faceted unset stones.
Diamonds and coins have some things in common: 1. They both can be graded and slabbed by a third party. 2. To be a successful investor, you have to know your market.
I don't have the skill of a diamond grader and I haven't put in anywhere enough time or effort in, to understand the diamond market.
Perhaps I may be a little more skillled in the coin category.

Quote: I don't have the skill of a diamond grader and I haven't put in anywhere enough time or effort in, to understand the diamond market. Nor do I know much at all, and the little reading I have done on the subject tells me that diamond grading is highly technical. It's not just color/clarity that determines the value of a diamond, but also the exactness of the cut. It's even more nitpicky than faceting sapphires, and I've been told that a poorly cut diamond will severely undercut its value. A gemologist friend forwarded me this pdf document on how to grade the cut of diamonds. While I don't understand much of it, I understand that any diamond of value needs a gem certification to asses value--you can't take people on their word. sel_69l, are you faceting Australian sapphires? It would be interesting to see pictures of your work. I've mined a lot of sapphire, and someday I'll get a few cut. They aren't very big rough--between 2 and 3 cts.

DVCollector:
My favourite gem material to cut is Australian yellow sapphire. You can expect to loose about 2/3 of the material off a rough piece of stone to yield a nice clean faceted stone, cut to refractive index laws.
I have a few books on mineralogy, crystallography and gem faceting, and a couple on jewelry, courtesy of my father's estate. I also have a couple of authorative books on the diamond industry.
If you cut to yield maximum carat weight from rough, still expect to loose half of the rough weight. That is what the cottage industry does in Sri Lanka does.
A very large proportion of World production of small diamonds is currently cut by small businesses in India.
Most of my sapphire rough has come from the Anakie area of Central Queensland, and I have purchased the material from traders who regularly visit there. I can't justify a return trip from Sydney on expense grounds.
I have, however successfully fossicked for some nice small blue sapphires from a place called Nullamanna, which is about 20 kilometres northeast of Inverell, in New South Wales.
You say that you have mined for sapphires. Where have you been digging? Yogo Gulch, I have heard, can yield some nice, but small stones. Is this site still active?
Sorry, I can't produce reasonable pics. at the moment, my camera is not good enough. Some current mobile 'phones are better than my camera! I will be spending around $1000 or so on a good camera and a new computer around mid next year.

I have some cognac diamonds from Argyle--but hardly flawless, nicer stones. I have a nice faceted cornflower blue Yogo, but I have never mined there...it's private property and for the most part inactive. I have mined placer deposits at Rock Creek Montana. Here is the color range (unheated) for 2-3ct rough. Heating will bring out the blues more. Someday, I'll get a few faceted.  I realize this is off-topic, so I'll stop...

Detection of diamond fake material is relatively easy, if you have the right equipment.
By far the most common diamond stimulant is cubic zirconia, which, to be honest, is a very reasonable gem material in it's own right, provided it is marketed that way.
Almost all natural diamond, except for one scarce type, is a good conductor of electricity. Cubic zirconia is an electric insulator. Two simple contact probes on either side of the stone, with a voltage across them, will very quickly distinguish between suspected cubic zirconia and a diamond. You don't need to take the stone out of the setting for this test.

@ DV or Sel- what about Moisonite? Is any that is on the market natural or is is it all lab created? I've been told both. so I'm a little confused...as per usual...

Gold and silver are better and much more liquidable.

I have never heard of Moissonite has having an investment potential. Interesting stuff, worth looking up elsewhere on the 'Net for those who are interested.

Sel,many of the "TV Jewelry" shows here in the US offer Moissonite in jewelry,usually cheap jewelry. I agree,there is no investment potential.
