My fiance has found a ring she kind of likes at Robbins brothers, but I cant tell if its a fair value or not (and everytime I go in there my skin crawls from the used car feel of the place). I''d prefer to purchase from a reputable online vendor, but havent been able to find a similar ring. So Two questions (I wish there was a settings forum, this feels offtopic, but I couldnt figure a better place?) #1 What are peoples general feel with the quality of the settings at RB? When they say platinum do they mean pure platinum (90% or better) or some lesser platinum mixture? Are the rings hollow or solid? And secondly, has anyone seen a setting like this anywhere? The important details being the square edges and the ring being smaller at the bottom than top? Thanks much for any advice!
