Posh Hidden Halo Ring (E+ VVS+)This diamond engagement ring evokes a sense of nostalgia while looking current and trendy. It has a cathedral shank where the arched shoulders are traced with round diamonds. Set high above the band is a showy 7 carat diamond center stone secured by four prongs with a diamond encrusted rail. Supporting the central gem is an angular bridge dotted with more diamonds for that unexpected sparkle.
