The GIA identified the Lesedi La Rona rough as part of an elite group of “super deep” diamonds formed three times deeper than most other diamonds. Rare emissaries of geological information, Graff donated fragments of the Lesedi La Rona to the Smithsonian Institute to help advance diamond research.
Possibly not I think it's size not sparkle that will be the thing on anyone's mind who gets a glimpse of this thing!I wonder how the ASET looks. Probably not great as it was cut to maximize weight.
@Dancing Fire's upgrade is here!!
I wish we knew the GIA report number - I want to see how many crown/pavilion steps it has, and what clarity it actually is. It looks like 3 crown steps in that close-up face-on picture, but I think only an expert like @Karl_K would be able to work out the pavilion steps!
You'd have to build a custom ASETscope for that beast
I'm intrigued by the last part of the article, though:
Do diamonds formed deeper underground have different atomic structures / internal graining/growth patterns??

Interesting, not heard of this before.
Hard to tell, but it is superbly cut with matching angles.I wish we knew the GIA report number - I want to see how many crown/pavilion steps it has, and what clarity it actually is.

I’d halo it
Cool to see the laser cutting at work, thank you for posting!
Just coming back to this, I found some interesting articles on GIA.edu about these SuperDeep diamonds - interesting reading!I'm intrigued by the last part of the article, though:

It needs a recut into an Octavia.
