Hi all,

I was curious if anyone knew how large (mm or cm) Ballas diamonds (ie., spherical aggregates) get, which still retain some translucency and symmetry?

Thanks in advance!

Cheers,

Hi Jim

John Betts has one for sale this week that is 8.89 carats and 10mm in diameter. I suspect that they do occur larger than this.

Regards
Steve

Thanks for taking time to respond, Steve

Yes, I saw John's specimen. He has also had some in the 12-13 ct range, but I was curious as to the size limit of fine examples.

Much appreciated!
