Complaint Review: Shah’s Jewelry

I ordered a VS1 .75 ct center, 1.55 ct diamond engagement ring which was paid in full by me. I went to pick up the ring the first time and it had a .5 ct center diamond, which was not what we agreed upon. The owner stated this was a mistake on his part, and offered to make the correction, which I agreed to. When I went to pick up the ring the 2nd time, he provided an appraisal showing that it was a .75 ct center, 1.55 ct tw ring. Following that, I had the ring independently appraised by 2 sources, verbally and in writing. The true size/weight is .55 ct center, 1.05 ct tw. The value is $2,475 less than the appraised value that the store provided, and less than what I paid for it, which he advertised as a sale/discount. I went back to the store with this information and he refused to issue a refund or provide any other resolution.
