Hi, my first post in this very instructive forum. Thank you advance for any
I am getting passionate about ruby and sapphire, and the more I lear the more the questions...
My 2 question relate to star ruby:
1) How can we sport a rough gem to be a potential star? I understand the need for a lot of rutile lines within the crystal, but it seems to be the case for most rubis..
2) now comes the cut of a cabochon out of such promising gem. How should the rough gem be cut to give birth to an asterism?

Thank you
