So a little less than 2 years ago I bought my now wife this engagement ring from
Peter Storm. I had a 1.43 ct. G; eye clean SI1; triple ex.
A couple months ago, the top came off (Halo, Main Diamond, and halo) of the band and was lost. Obviously we were devastated. She loved her ring.
Insured value was $18,500. I contacted jeweler where I purchased, and she got a repair estimate from Peter Storm, which was $15,000. That was reasonable to us. USAA required we have the ring sent in for their gemologist to review. Their repair estimate is $9,200.
Do I have any ability to refute their estimate? I assume they picked a virtual diamond that is not as high within the respective grades. The setting had 150 diamonds totaling 1.40 ct; f/g vs1 and a sizable amount of gold given its a ring.
