Re: which (ring) setting allows the most light into the ston
I like an open cathedral more than a closed, and a u-prong, channel, or trellis setting is pretty also. Technically, if you have an ideal cut stone does it matter what setting you have:
since with the well-cut stone all the light enters and exits out the top?
I wonder if the setting style isn't more to personal taste, assuming an ideal cut diamond, and should have little to do with performance.
