I have this stone shown below and 14 baguettes. And while I can rearrange things to my hearts content, it's not really the same a seeing a setting. Photographing the spinel upside down on a brown background is doing it no favors. it's a really nice red.
That sounds like a fun project! Are you thinking of setting the spinel E/W? That might look cool if you are thinking of placing the baguettes end-to-end all the way along the shank.
I don't know yet which way I want to set it yet which is why I'm looking for pictures. It's not a very rectangular stone though, I believe the dimensions are 7.5mm x 7mm.
