I would like to have my diamond E-ring re-set in a halo setting. I love the Ritani micropave setting but I am fussy about color. I want even the small side diamonds to be D or E and I think that most of the Ritani settings are in the G range. I would love to go with the Cartier halo but I want to use my own diamond and Cartier will not do this. Does anyone know of any great quality designers with halo settings that you can supply your own diamond?? Thanks!!
