This will be random, but a friend of mine pointed me in the direction of consumer law so maybe you could help! My fiance recently proposed and I have a diamond ring with a GIA certificate. I went to get it appraised with a different jeweler yesterday and we discovered that my diamond doesn't match the certificate. They are very close, but my actual diamond is better in color and worse in clarity with the everything else pretty much the same. My actual diamond is valued higher than my certificate. I called the original jewelry store and we figured it all out and basically they accidentally swapped the certificates (who knows how long ago) and priced my diamond based on the certificate specs (even though all the handlers kept saying the color of the actual diamond was better) rather than the diamond spec. So now the store wants me to pay the difference to get the correct certificate which was $4k that they discounted to $2.4k. I want to know what kind of rights I have. Am I legally required to pay? This whole issue is their fault for not double checking numbers with the diamonds etc.My fiance bought the diamond based on what it looked like and not the certificate specs because he's not an expert and those specs mean little. Also, to clarify, the certificates were switched prior to him even looking at the diamonds because from day one, the handlers were all confused about the color and saying how the diamond actually looks better than it should but never did anything to investigate. What do I do?!
