Engaged/married? What did you do for rings? - Page 5

post #61 of 79
My friend's wife lost her engagement ring and they replaced it with a synthetic diamond from here: http://www.diamondnexuslabs.com/prod...oducts_id=1061 He says they look incredible and come with GIA certification. They are IF flawless with ideal symmetry. The prices are quite reasonable, only $250 for a 1.5 carat. I'm seriously considering getting one of these. My girlfriend is from a different country and doesn't quite understand the whole diamond thing. All she knows is that she has to compete with the other women at work. I told her if we want to buy a house soon, there is no way we can afford a $10K rock. She agreed. If she wants a blood diamond later on I can save up for one after we have the down payment on the house. I think getting one of these is great regardless because you can keep your real diamond in a safe and not have to worry about losing this one. They replace the diamond if it is ever lost, fades, etc. I'm just going to go with the round brilliant but the Asscher cut is very cool. What is a good setting metal? Right now I'm just going to go for a simple 6 prong Tiffany solitaire. Do you prefer white gold or platinum? Any other metal combinations that work well? I am reading that the Rhodium plating on white gold fades easily. I'm also reading that Palladium/White Gold and Iridium/Platinum are good to get, but these alloys seem hard to find.

palladium gold is nice. It's a better alloy than a nickel based white gold (and I personally do not like yellow gold).

I'm a big fan of lab-grown diamonds (the concept of them, never bought one), there was a ?wired? article a few years back that did a really good job detailing the saga of the artificial diamond companies. One thing that stuck with me and really bothered me was debeers' big push to prevent them from calling them diamonds similar to what is done with pearls. A diamond is a scientific term for a certain organization of carbon atoms, it doesn't matter how it was created. If it has the proper structure, it is a diamond (I can understand pearls since pearl doesnt refer to a compound specifically).

That's not GIA certified, that is AIG (American International Gemologists) which has been known to produce grossly inaccurate appraisals. I also don't see how any self respecting diamond or gem grading lab would even issue certificates for diamond simulants (which are different from man-made diamonds). Not that grading even matters in simulated diamonds anyway since they are manufactured to be free of inclusions and to a specific color tint. If I had to guess, the website above is selling grossly overpriced CZ (Cubic Zirconia), possibly with external coating. Nothing wrong with CZ or other diamond simulants or man-made diamonds as long as you are 100% certain of what you are purchasing. The world of diamond simulants (which generally do not share the chemical composition and physical properties of natural diamonds) and man-made/synthetic diamonds (which are usually all carbon) is very murky and is full of conflicting statements, claims and misinformation. Buyer beware.

yes, i dont believe they are GIA certified , but so these are real diamonds just man- made that is all? i did not know they come at those prices did you ever see one up close and personal? can they be distinguished by non professionals from real diamonds?
i may look into one of these. thanks.

There are diamonds being grown in labs now that are identical in chemical structure to mined diamonds. Diamonds are nothing but a lattice of carbon atoms bonded tetrahedrally to 4 other carbon atoms. There's nothing mystical about them. These new man-made diamonds are nothing like CZ and the GIA has stated as much. The diamond cartels will obviously create as much misinformation about this as possible, however the diamonds sold by certain companies have the exact same chemical structure as a diamond that comes out of the ground. Having said that, you should certainly do some due diligence on whichever company you decide to purchase from, as I'm sure some don't sell the real thing.

No. A diamond is a diamond, plus or minus inclusions and impurities. I believe that most labs do laser inscribe the stones, but it is not visible to the naked eye and does not affect the brilliance of it at all.

Not sure if you were agreeing or disagreeing ... Yes, that's what I meant when I said man-made diamonds consists of only carbon, while Diamond simulants or imitations, like CZ, have other elements added. De Beers and the diamond mining industry of certainly have a vested interest in keeping man-made/lab-made diamonds from being a viable less expensive alternative to their gemstones. Do to the technical challenges involved, gem quality, colorless, engagement ring sized manufactured diamonds are neither widely available nor cheap. I think De Beers still has 5 to 10 years before they have some real competition and then we may see them dropping natural diamond prices on the wholesale level. From what I read, "fancy yellow" and other colored diamonds are either and to create in a lab so if you are in the market for one of those, a manufactured diamond may be a good option.

Btw TC, if you read the FAQ on that site:

What are your stones made out of, and how are they different from natural diamonds?

A: Diamonds are made of carbon only. Our stones feature carbon and eight other additional elements: oxygen, sulphur, iron, cobalt, nickel, yttrium, zirconium, and hafnium.

So the ones on that site aren't real. Is anyone aware of a company that produces colorless stones? I know Gemesis does yellow diamonds.

Q: So Diamond Nexus gemstones are not CZ. What makes them better?

A: The problem with CZ is that they’re not as strong as diamonds, and also they’re much more porous. This means that they can break or chip at any time, and that they will absorb dirt and oils over the years to become cloudy and unattractive. Diamond Nexus gemstones are made to be much harder and less porous – so much so, in fact, that their properties are almost exactly identical to natural diamonds. This means that, unlike CZ, a Diamond Nexus gemstone will never break, never chip, and never lose its sparkle. It can even cut glass.

This is true. I will get one and see how they look. If I come into some money, then I can buy a real one, otherwise one like this may have to suffice for now. As long as we both know what we're getting I don't have a problem.

And yes, I'm a bit dyslexic. It is AIG not GIA, they must do that on purpose.

Hmm, there has to be something weird with those because synthetically-grown diamonds are increasingly difficult to grow as they approach the one-carat size. They are also very difficult to grow in a white color although they are nearly pure carbon.

afaik apollo is the only company that is doing them colorless. Gemesis only does colored diamonds. Apollo also seems to stop at .6 carats from what i could tell on their website. Still, it will be nice once they've got a better handle on the tech to start pushing them out with less difficulty.

The general consensus on Diamond Nexus Labs based on a google search is that they're misrepresenting their cubic zirconium products as "synthetic diamonds."

And from what I've seen, there's little difference in price between their colorless synthetic diamonds and "natural" diamonds.

synthetic dismond is the same as synthetic sapphire, spinel, ruby etc. same chemical composition etc. just man made. noone but a pro will be able to tell if you have a synthetic diaomond. the only way would be to look at the inclusions,look at the fluoresence under high and low UV, and with a synthetic diamond tester and other lab techniques. but from the naked eye its pretty much impossible.

Well I've been poking around some more and it does seem that Nexus diamonds have not gotten the best reviews online. I will have to buy a real diamond after the house is squared away anyways. I just need something that will last a couple years. Looks like here is another site that does real synthetics http://www.chatham.com/diamondintro.html but they only do colored diamonds. Has anyone had experience with the Asha simulant diamond? Their prices are quite reasonable as well and have gotten better reviews. www.betterthanadiamond.com I may buy a few different simulants and then compare them all in person. Many of them seem to be CZ with added stuff, which is fine with me if it makes them harder and less porous.
