I bought Niessen platinum tensions ring with 1.01 carat excellent rated diamond in early 2002 for my wife. Till last weekend everything was ok - but last weekend, when we were in the theatre the diamond "felt out" and we lost it somewhere. At the first moment we were shocked and after that, when about 12 people try to find the diamond and we didn’t succeed my wife became said and I''m very confused and disappointed.
When I bought the ring Niessen Company claimed that there is no chance that diamond could be lost and within I believe Niessing gave me a lifetime warranty and guarantee that the diamond will not be lost. I paid for the ring €3,500 and for the stone €10,000 and today I have very unhappy and said wife, ring without the near perfect stone and the feeling that something is wrong here.
I contacted Niessing and they replied as:
"The examination of the ring did not show any evidence of a fault in material or workmanship. But there are clear
marks on the ring indicating that the ring was subject to a hard stroke or hit from outside which led to the loss
of the diamond, i.e. an impact that normally does not occur with the regular daily wear and tear.
As a result Niessing cannot assume any responsibility for the loss of the diamond".
I was shocked, first because if really hard stroke or hit from outside results realizing the stone from the tension then my wife certainly felt it as well, but we were in the theatre and nothing special happened.
Is there anyone out there who could be so kind and please advise me what to do.
