When you can buy a 200 ct diamond for £60
on: August 26, 2007, 18:51:09 PM
what is the point in buying a real one when the only difference is the certificate and laser marking? As the page says 80% of the diamonds being sold out there are synthetics and you cant tell the difference. You might as well save the money and extend the honeymoon.

Because a simulate is just that... a simulate.

Carat is just a measure of weight so I could have a 200ct carrot. Doesnt make it a diamond. :)

Would that be a big carrot thought?

But 30mm is to big to put one in my teeth :(

1 carat is 0.2 grams so its not a lot (200ct = 40g).

Its just used for diamonds cos theyre so small.

Anyone know if they really do make diamonds that are indistinguishable from natural diamonds (by naked eye or even better by experts)?

They are damn expensive those real diamonds :)

yep - you can actually make real diamonds in a lab AFAIK tis just another form of carbon after all - IIRC some crazy oriental/asian scientist made diamonds from plastic litter he picked up on the beach (using a bunch of high powered lazers) - only they arent any good for jewelry as they are basically microscopic - I think they do have some application in drilling equipment for the oil and gas industry.

Great way to recycle!

More like there is a fake, such as cubic zerconia, and a synthetic which is basically a real diamond.

Was a programme on TV about it last year, basically a machine that pressurises and heats carbon to huge pressure and temperature. The diamond crystalises from the carbon. Early ones had problems with purity but later ones are so good that DeBeers cant easily find a difference with the machines and money they have - which is why laser markings and certificates have to be provided.

[edit] found the original programme script-

http://www.bbc.co.uk/science/horizon/1999/diamonds_script.shtml

And if you have ever looked at the bling on bid.tv you can bet your ass that the stones that are not guaranteed natural will be synthetics.

There are lots of ways of making diamonds and there are lots of places to mine them.  Theyre really not that rare at all.

Its two diamond cartels who convinced the world that diamonds are somehow uncommon and worth money.  They then also branded them and gave certificates to stop people just selling the ones in the mines around the world.  Its a total scam.

A diamond from a mine or a lab in Russia is exactly the same material as one out of a DeBeers mine.  Theyre not replicas - theyre the same exact thing.  they just dont have a certificate which is just a piece of paper.


But yes, there are systems around the world that just nuke carbon with high pressure and turn it into diamond.  Thats how most laboratories get their diamonds.  They sure as hell dont pay full whack for one with a piece of paper a company tacked on the end.

There was also the issue that African diamonds were gems while the identical stuff mined from South America got termed industrial diamonds. As SteveF says its all a fix by the big companies to keep profits high.

[edit] If I got a nice big ring, for all four fingers, made with those - would the police still term it a knuckleduster? :twisted:

Except its not a synthetic diamond for £60.

And Simulant is not Synthetic spelt differently.

They use the term lab diamond which indicates a synthetic. That isnt the point though, the item is stated as indistinguishable from a real one by you, if some glib shop assistant told you that it was a real diamond you wouldnt be able to tell the difference.

The terms used throughout the entire ebay advert are simulant.

Lab created or not it is still not the same. You are spending £60 on what could be 200cts of glass, or cubic zirconia.

In fact cubic zirconia would fit considering its not a natural element, and is synthesised within a lab environment.

Go right ahead if you want to, but you can buy quite substantial amounts of that for close to £20 from lizzie dukes in argos, and that includes it being mounted.

metal is right - this isnt a carbon lab diamond

Its a lab created replica.  That could just mean cut glass made in a lab.  By the looks of it this is cubic zirconia or something forced to crystalize like diamond (instead of in a cubic structure).

But your principle is right, you can buy lab diamonds that are diamonds for much less that are indistinguishable by everyone.  The item you linked just isnt one of them.
