G & G Winter 2014 - Argyle tender

[Marlow]

Interesting too is that the annual expected produktion is 20 000 000 ct - " only" 0,1 % is pink.

But that mean they produce 20 000 ct pink diamond each year - since 1985 - 30 years ....

around 600 000 ct - or 120 000 gr - 1 gr = 1 ct finished stone - 120 000 ct - lets say 0,10 average weight = 1 200 000 pink diamonds!!!!

Much much more then many collector gems like taaffeite, benitoite or russian demantoid or brazilian alexandrite.

Totally agree about the fact that you can't rely solely on a GIA report for color, and a system that grades intensity within a particular grade would be a great way for less informed consumers to make a more informed descision and for me to learn to judge saturation better. After seeing a lot of FCDs on various sites and a few IRL the differences in intensity and modifiers within the exact same colour grades really bothers me. It wouldn't if GIA's colour grades didn't basically dictate the price it'll sell for. Oh well. People who don't already have specific preferences and don't research or look around enough probably don't care if their deep pink is a little brownish.

I like the oval I posted a lot despite the brown. I have yet to see a pure deep pink without modifying colours (whether indicated on the GIA report or by my eyes).

This is a very interesting topic for me and I'm researching just how GIA decides on a colour grade. I wonder how common it is for a diamond to be graded again and to return with a slightly different grade.

Marlow, yeah, even colourless diamonds are marketed to be very rare. So you can imagine how rare they would market less common colours to be. Of course, some colours are very rare or even one of a kind. It's amazing to me how many natural colours diamonds can come in.

This is a good example - 610K pct!!!!

A "red" diamond - same problem with the color...but the inclusion would drive me crazy!!!!

Well, diamond is more in demand due to its hardness, luster and the way it breaks up light, and of course its marketed to death. There are lots of gems more rare than diamond, even many rare colored diamonds, but they just don't have the same appeal or even beauty. For example, I've never seen a really beautiful taaffeite (maybe they exist??). I have seen demantoids that are on par with diamond for beauty though.

Well, you'll never see a pure blue, even if its graded fancy vivid blue, without grey either.

The most intensely saturated diamonds for their hue are probably yellows. I've seen some that really glow.

Taaffeite - I love them and I collect them but they def. look like 10 $ spinel - no question!

And of course it cost a lot of money to find and produce diamond. At the moment I think it is a bubble - and telling that 2020 the Argylemine ill close - I don't believe this - look at some southafrican mines. And we don't know how many diamond they hide - which are not in the market.

Yes, it seems as if they grade blues based on 'relative' colour to other blue FCDs and not in comparison to, say, saturated sapphires. Otherwise they'd all be greyish or grey blues.

I have yet to ever see a "sapphire blue" fancy blue diamond. I don't believe they exist. There are lovely fancy greenish blues, or blue-greens, though, with nice saturation.

The "blue moon" diamond (pictured) is probably as blue as a fancy blue can get. It's graded fancy vivid blue, but even within that saturation level, it's probably at the more saturated end of the sub scale. However, at least many blue diamonds like these have gorgeous sparkle and life to them. I would take the "blue moon" in a heart beat, and because I think it's beautiful, despite the grey. Some are overly grey though, so much so, you have to "imagine" the blue, even if its graded with a blue primary by GIA.

Oh, TL.

Yup, I think I agree. I love your description of 'imagining' the blue. You've posted that a few times before, and each time I read it I understand what you mean more.

Yes - really bluish grey or just a " cool" grey.

My small cushion/oval has a cool deep grey color - and a strong greenblue fluorescence. But is def. not bluish grey...

I saw a fancy blue at a museum once, it was from a Tiffany piece, and seriously, it was so pale in tone, that the saturation was so lacking, the blue was barely there. If you walked past it not knowing it was a fancy blue, you would think it was a regular white diamond. That's not to say I wouldn't take it. Don't get me wrong, I would take ANY blue diamond, but if I were Laurence Graff, it would have to be very saturated to be in my personal collection, or really huge.
