Hi all, Long time lurker first time poster here. I 'm after some design advice please. I have just collected my half eternity band from my jeweller. Its a six stone, 0.6 per stone band (tcw 3.63) I had it set in four prongs but had my heart set on shared.I also don't love how the four prong makes the rounds look more square. I'm getting used to the prongs in between my fingers but do you think a shared prong is a bad idea security wise? I would hate to loose a stone. Thank you.
