If a thing exists in the fine jewelry world, and one is having
trouble finding it, chances are New York Findings has it. In this
case it is so. Their catalog is indecipherable, but they have the
goods. Rondells are rd-series. 5mm pave (depending on what you mean
by pave-many definitions of that) is maybe rd-22, or rd42. They have
white gold clasps, also, but there are hundreds to choose from.
