The Ruby you definitely need to find out about treatments and it looks fairly heavily included - is it?
The middle Indicolite is nice and my favourite of the bunch. I hope this isn't too dark as these have a tendancy to be.
The right Indicolite looks heavily included and has an enormous tilt window so unfortunately the photograph doesn't do it justice. It probably looks much better face on.
I would also be curious whether the tourmaline on the right has a closed c axis, as it looks like it might. If so, what happens when viewing the stone from the side - is it a dark wall?
