Diamonds International Flawed Ring Designs and Horrendous Customer Service , Internet

Purchased an engagement ring from Diamonds International while on a Carnival cruise in Cozumel in July of 09 and then went on-line to purchase a matching wedding band from DI's website in November for our wedding on 12/31/09.  Prior to the wedding my wife noticed that the fit for both the bands was not right so we took them to our local jeweler who re-sized them both.  After our return from our honey moon in mid January the fit for the wedding band was still not right and before we could return to the jeweler a diamond had fallen out much to our dismay.  Upon close examination our jeweler said a number of the diamonds were loose on the wedding band and they were having a difficult time tightening them.  After returning the ring all was fine until a second diamond went missing, (this time it was one of the begets) in late August.  We returned to the local jeweler and contacted Diamonds International to open a claim.  After taking all of our information as well as faxing all of our purchase receipts for both the engagement ring and wedding band to DI we waited to hear back from DI's customer service supervisor "Bella" who said a higher level had to make the decision to replace or refund our loss.  By this time my wife and I are devastated to be without both rings for going on a month now.  "Bella" after several days sends us an e-mail informing us that our claim was being denied since DI's return policy states that ring can only be returned or receive money back with-in thirty days from the date of purchase and any alterations by anyone other than DI or TI voids any warranty's.  After the decision by DI my wife and I are completely beside ourselves.  While discussing options we talked again with out jeweler who again took another long detailed look at both rings.  Their analysis was even more distressing -- it appears that both the engagement ring and wedding band were "cast" with the smaller rings in position rather than adding them later and because of the flawed casting design there was insufficient metal to hold the diamonds in place securely and it was a basic design flaw in the bands.  While both bands had loose diamonds the wedding band was especially bad and even adding more metal would not solve the issue and the only resolution would be for DI to replace the wedding band with a new band that hopefully contained enough metal to hold the diamonds.  We asked our jeweler to contact DI to explain the situation with the rings which they did but DI essentially said "NO DEAL" because we had re-sized the rings all warranties were void.  Needless to say my wife and I have two diamond wedding rings worth in excess of 13K $ that cannot be worn since the diamonds in them are in danger of falling out at any given moment and we are dealing with a company (DI) who is peddling rings with faulty designs or cutting corners with the amount of metal (18 ct gold) to cut cost and who will not stand behind their product(s) and does not know the meaning of customer service.  I'm sure some who read this would say "caveat emptor" let the buyer beware, we say it should read "caveat DI" beware of Diamonds International.
