Man Made Diamonds Help!!

Recommended Posts

Laurent,

 

It depends on who you mean by 'most' labs.  GIA will grade them, rather like they'll grade anything, but there are some important differences.  The color and clarity scales are different than the scales used for natural stones for example.   AGSL won't grade them at all.   HRD won't do it either.

Here's another question.  Where do y'all figure the BTD lab-made rough is coming from?

Well, they claim they're coming from Takara at the moment.  I see no reason to expect that to be wrong.  It's entirely possible, probable even, that Takara is outsourcing some or all of their processes rather like most of them do, but it's definitely proprietary exactly who they use for what steps and why.  It might even be several different suppliers at once.  Most manufacturers, not just of diamonds, try to have distributed supply chains.

Between the GIA, IGI, EGL and some of the lesser labs, I find that more labs are willing to grade them than not.  I agree that the grading scales are different or at least condensed - GIA for example will call a stone VS but not VS1 or VS2, but the fact remains that they will grade them.

Don't mis-read me:  I excluded those from the list as they do not grade lab-grown.  The HRD and AGS  are among the top labs although I do wish the AGS would build greater global brand recognition.

What are you looking for?

 

I'm going to guess that what you're after is a big beautiful white diamond for cheap because some magazine article or website told you they could be manufacturered for next to nothing and that the diamond universe has changed. You're right, you're not going to find that. Sorry.

 

If your budget or psyche doesn't support diamonds, and I definitely understand, there are several alternatives to consider. CZ's look a lot like diamonds and cost almost nothing. I'm sure you've looked into that but try it again. For the most part, CZ's are pretty nice and paying 50x as much for one doesn't make them better. Superb ones can be had for about $10-40 at most neighborhood jewelry stores. The labor to set usually costs more than the stones. They do have some durability issues and will need to be replaced occasionally but are otherwise a perfectly acceptable diamond alternative. There are lots of other gemstones like sapphires that are historically used in engagement rings that can be LOTS cheaper. $100 goes a long way with most other sorts of gems. You can spend big bucks there too but it's less mandatory. Small diamonds are fine. It's a symbolic thing and it simply does not need to be huge and it doesn't need to be VVS. Something under 0.25cts in a natural diamond can be had for a few hundred dollars and you most definitely can make a lovely and meaningful ring from one. People do it all the time. No stone at all even works. Gold and silver bands are readilly available and actually have been the tradition for considerably longer than diamonds.

 

 

I was getting ready to purchase from DiamondNexus or MiaDonna and came across this thread. So if I don't care whether or not they're real lab diamonds or CZ but I want something that will look real, what is the next best thing? From what I understand, if they're not "real" lab diamonds, they're all CZs and you shouldn't spend more than $50 on it? Am I right?

 

I'm new to all of this. I already have a real flashy diamond ring. I'm thinking of going simple solitaire and looking to spend less than $1.5-2k on one that will fool most untrained eyes. Where is a best place to go? Or what type? And what is moissanite?

 

Thanks

Good quality CZ will fool most people without a loupe and some training, at least until abrasion of facet edges happens. It can take a few months or a few decades, depending on how hard you are on the jewellery and how often you wear it. This is not an argument for the "coated" stuff, BTW - I don't know any study on durability of those stones, but I doubt it's much better than the uncoated version. $50 for a loose CZ is a lot; if you include setting labour, it's probably slightly at the low end. How much you spend in total is really a question of how much you want to spend on the setting: you can go from $50 for a dinky silver thing to several thousands - without moving out of the "solitaire" design.

 

Moissanite is another type of diamond simulant. In my opinion it looks significantly less like diamond than CZ, but it is much harder (and much more expensive - last time I looked it was several hundreds of dollars per carat).

Why do you think moissanites look less like diamonds that czs?  Just curious.........

FWIW, I agree with him.  The biggest giveaway with CZs is that they're too white.  The giveaway with Moissanite is that they're too green.  The real problem with Moissanite is the price.  They're not really any better looking (to me), they're still fake, They're not actually all that much more durable, and they're 50x the price.

Interesting. Perhaps because I see (faintly) coloured diamonds as much as "colourless" ones (or in fact more often), the thing that stands out to me with moissanite is dispersion. It just doesn't look right - way too much fire.

Thanks Neil.  I wonder if the pricing of moissanites will change now the patent has expired. 

We'll, it hasn't happened yet.  The patent ran out in August (It's November now).  I don't actually have a clue how long it takes the knockoff artists to get up to speed on this sort of thing and 3 months is a little tight but Christmas is coming and I would expect that to be on their calendar.
