Beverly diamonds product not as advertised los angeles Internet

I purchased an engagement ring from Beverly diamonds.  They told me it was graded SI, f color.  They included an appraisal from a company my insurance carrier would not accept " Diamond laboratory of America'  claiming the ring I paid 5200.00 for, appraised at 14, 626, and retials for 8126.00

I had an appraisel done locally for my insurance carrier. It was barely able to appraise at 4800.00  and was only I 3 nowhere near SI.   

Buyer beware, they say they do not agree with the appraisal. too bad.   

I wish I had paid a bit more and bought from a reputable jeweler.
