Doesn't get any simpler than this. :)  Keeping it Simple features a 2mm rounded shank with a simple cupped prong which we can do single or double.  The renders feature a 7.5mm x 6.8mm rectangular cushion but can be modified to whatever you want. :)  The prices below reflect casting from our Stuller bench but can also be submitted to our master bench for Tiffany/Cartier/Harry Winston like finish/quality.  If so, simply email me for a quote.
