The issue with clear rubies is that they and modified rubies have the same clarity. A modified ruby, astrologically worthless would cost a 100$ and a cheater can sell it for 150,000, there are many such cheaters out there, thus I warn all my clients about these things prevalent in the age of Kali.
Do observe her ring finger as it bears another what appears to be a ruby of about 8 carats.
Here I see what should be a white sapphire, I think it is a 50,000$ gem.
