Hello all, first post here so cut me some slack
Here's my story:
I purchased an engagement ring for my fiancee (now wife) and we're having some issues with it.
18k band with small diamonds (total .64ct) pave set on top half of the ring
1.7 princess cut F clarity VS1 center stone set with 4 prong platinum head
I already had the center stone when my wife picked out this ring. The jeweler recommended using a platinum head to better secure the center stone (so I agreed). The jeweler had to send the ring out to an "out of house" jeweler to have the existing 18k head swapped to platinum and the stone set. We reluctantly agreed.
We got the ring back before the wedding and it looked lovely, very brilliant and beautiful. Unfortunately after the honeymoon (she swam in the ocean with it
) it looked dirty and we noted a slight yellowish color/tint to the stone. I chalked it up to being dirty. We had it ultrasonic cleaned at the jeweler but we swear we still see some yellow color in the stone that was not there before.
We took it back and they agreed that there might be something up with it and they may have to send it back to the out of house jeweler.
I know little about technicalities of jewelery. I am wondering if something with the soldering/welding the new head on is reflecting some color through the stone (the stone is set flush in the "V" shaped head).
What do I need to ask about the work that was done so I ensure this is taken care of properly and the work that was done was done 100% properly? It wasn't cheap!!
Any advice is much appreciated!
