invisible or blind setting stones

[Green Monster]

Thankl to Nic and Jason, same article...
but just what I was looking for. I have never seen mention of stones grooved below the girdle before, it all makes sense now.
I would have thought that grooving the stones would have knocked alot off their value, not something I would want to do to a quality stone.

Jason, what holds the four meeting corners in place in the centre of an illusion setting?
cheers

If its invisible, Nic, how will we find it?

Late to this one...

There's been a lot of discussion on Ganoksin about this setting technique recently - there seems to be a consensus emerging of it looks nice, but don't even think about reworking it later... Along with it *will* need reworking.

I had already thought it was a no go on reworking after seeing the instructions for construction, definitely some skill involved in doing the setting in the first place. Fulll respect to anyone that does it.
Cheers
