MakeUMoan asked:
Why is there such a substancial markup in price for diamonds certified by expert organizations? Is a non-certified not a real diamond? Is a certified diamond worth the extra cost involved in purchasing it? Are the qualities of a non-certified diamond (clarity, cut, color, etc.) identifiable if no expert organization or gemologists has given it a certification?

Certified means that they’re real. Non certified means that they could be real but that they probably aren’t.

I don’t know about your certified and non-certified, but I do know about “blood-diamonds”. I’m not sure if there’s a connection or not.
Lot’s of rebel groups in Africa, have taken over the diamond mines, and are now selling them cheaper than the normal market price to bring in funds. To purchase these diamonds is, essentially, funding terrorism.

Certified means its been given a grade and a certificate that states color, cut, and clarity. They have more sparkle and brilliancy. They also usually contain a number engraved on the rim that can be traced if stolen and are insurable.
Non certified diamonds are just lower grade diamonds that have not been given a certificate and usually contain flaws more noticeable to the naked eye. There is nothing wrong with these diamonds they are just less valuable and cost less.
When you purchase a certified diamond you are getting high quality. If you purchase a certified diamond the return on it will be greater if you decide to upgrade or sell it at a later time. Diamonds are an investment.

A diamond is a diamond. In the United States, and probably in most countries, it would be against the law for a store to call something a diamond if it is not. A certified diamond means that its qualities have been measured and quantified, and printed on a bit of paper that you get with purchase. A noncertified diamond means that its qualities have not been necessarily measured in any way. The diamond may be of higher or lower quality than stated. Certified diamonds are more expensive than non-certified because not only do they look pretty, but they have the papers to prove that they are that pretty and valuable, and they usually have a serial number that gets stamped on the piece of jewelry and on the certification paper, to positively identify the piece.
It’s kind of like the difference between a purebred dog and a dog without any papers, that looks the same. If you’re interested in the investment value, or if you’re spending more than a hundred or two dollars, you probably want to buy certified, for the guarantee of the stone’s value. If you really don’t care about quality and just want a pretty diamond, or if you have a habit of losing things like I do, uncertified probably meets your needs.
The qualities can be identified on an uncertified diamond; lack of certification simply means that the qualities haven’t specifically been measured and recorded. They are certified by independent groups, not by the jeweler who’s selling it to you.
