Matt did a great job appraising my diamond engagement ring. He checked every aspect of the ring thoroughly, and included all the details in the final report. This proved very helpful for insurance...

Matt did an awesome job with my appraisal. Super professional and honest!! Also gave me a sheet of questions to ask the insurance company about the extent of their coverage which was very helpful.
