Tapered baguettes. Please help!

[asscher trouble]

I have a beautiful engagement ring with a 1.64 Asscher cut stone. I''d love to add some tapered baguettes as side stones. Can anyone please explain to me what I have to look out for in tapered baguettes (quality etc) and how much they are "about"?

And whether you think they would look good with an Asscher cut centre stone.

Thank you very much!
