Hello everyone,

Last day my friend show me his collection a very large of rounded shape Black Diamond. its was 129.5 crt.

I searach in google and found this link emirates247(dot)com/news/emirates/world-s-largest-black-diamond-on-display-in-dubai-2015-12-25-1.615066

but its only 88 carats after cutting and polished.

Any other biggest one do you have??

It might be big, but it does not look impressive, pretty dark, no shine.

YEah... its look no shine in this photo. Maybe its affect by the poor picture quality or low camera resolution.

Maybe it's just a fake - muassonite... Shown as diamond. There are a lot of black muassonite at ebay and so on market

i am not sure if a gemologist has missing the 'Moissanite' word in his identifications results.

Black diamonds are usually irradiated to make them black.
