Question for all you jewelery lovers. I am having a 5 stone diamond (1.50 tcw.) anniversary ring made, in a trellis design. The jeweler who is making the ring wants me to upgrade the metal from white gold to platinum, he said that the quality of the diamonds is very high and that the gold will not do the diamonds justice, the price jump is extreme, from a $575.00 setting to at $1,800.00 setting, does the price sound right to you and is there that much of a difference in look. Thanks for you thoughts.
