In no way am I making light of your post. It is very interesting.
It is truly a remarkable fine.
Some Arab will probably purchase it…or Soros. (They are equally despicable.)
Thanx
No doubt you have some reference tables there.
It appears to have an octahedral termination, which is consistent with a diamond. I don’t think any more can be said about it from the picture.
That’s not a diamond- that’s kryptonite!
Liz Taylor is gonna be pissed!!
The Russians figured out how to make artificial diamonds. The bigger ones just require more time. Is this a really big artificial one they are trying to pass off as natural?
Or maybe more like a greenish fluorite cleaved to bipyramidal crystal habit. It's a hoax or a con in my opinion. Other than the cubic crystal form there's nothing diamond-like about it.
I don’t believe it’s a diamond, but I’ll be happy to accept 10% of it’s auction price.
I have a bunch of those in my house...but they are hard to keep tight.
I bid 300 quatloos for the newcomer.
So far you’ve said nothing that indicates you have any knowledge whatsoever of mineral identification either in hand sample or under a microscope. All you’ve said is that I’m wrong and then insult me with your condescending remarks with vague claims of flawed logic based on small differences in scale and “reference tables”, whatever the heck that’s supposed to mean, when I clearly pointed out the effects of scale on known examples of very large phenocrysts. Do you really want to know what “tiny” diamonds look like? They are very often but not always euhedral, either isoctahedrons, cubes, doubly terminated octahedrons, or tetrahedral, and very often with reentrant cavities of the same or other forms. Since diamonds have perfect cleavage along the [111] face, those forms will be apparent in crushed or distressed specimens. Rounded terminations and ghost faces are common too as the thermodynamic conditions and chemical activities change during formation especially in larger stones as they travel up the pipe into new regions of chemical stability. Naturals can have a wide variety of colors but are usually colorless to yellow to pink to black. Flecks of graphite, foreign inclusions and other defects are fairly common too, and cutters learn to work around them to bring out the best in any particular gem quality stone. Only the finest investment grade diamonds kept in vaults are truly flawless. Synthetics like those used on diamond drill core bits are usually a very distinct green due to small amounts of elemental iron and display the same shapes described above for natural stones. The characteristic greasy or oily luster along with a high refractive index that captures light and “funnels” it along preferred directions is apparent from unfaceted sand sized grains under a microscope in ordinary unpolarized light right up to the largest specimens known both in matrix and as alluvial placer. They don’t call it adamantine for nothing.
And the picture was taken far away and it is blurry too...
Yep. They need to hand it over to me.
And... then I’ll send Spacebar a ticket and we’ll split it see.... yaaaagh, yaaaaagh. And that’s the way it’ll be, yaaaaagh, yaaaagh.
And nobody goes to the coppers, now, yaaaagh, yaaaagh.
I don’t know if that’s a diamond, but isn’t that cellphone a collectible on EBAY?
Not just Russians. Some fine fellows in both FL and LA are producing artificial diamonds that are so perfect, the only way you can tell them from "natural" (whatever that is) diamonds is that they are too pure.
Diamonds are a racket. I can't wait until you can get them for a dollar a carat.
Nice bit of information there, Spacebar. I bet others might think that you Googled to get those facts, but I know that it comes right out of your head, having known you since that day I met you on the bus back in 68’.......
