I was given a CZ engagement ring on December 21, 2008. On January 7, 2009 I returned the ring to the company for repair. A side stone had fallen out and the center stone was loose. I received the ring back on Jan 31 (well over the promised repair time). The center stone is now pushed down into the prong setting and crooked and the side stone that had fallen out has fallen out again. I have called and emailed so many times and no one will return my calls and all emails from the company tell me they are waiting to hear what can be done with the ring. I have not received a satisfactory response. read full review »
