I have an I color 3.58 carat pear diamond. I had it set in a very wide platinum band with inset side stone. I can sometimes see a slight tinge of yellow in it the center stone in certain light. My jeweler suggested re-rhodium plating the prongs to try to minimize it. Not sure if that will make a difference or if I am fighting a loosing battle and should either live with it or find another stone. Any thoughts??
