I know this sounds crazy but I found a good diamond from a vendor here. Due to great pricing, there is no refund policy
However, I am planning to use Justin K - Manhattan Appraiser - to consult on my behalf PRIOR to purchase. I am in Chicago. Is this a stupid move? Should I pay more and have the money back guaranty? Is it abnormal to have the buying and appraisal done in another city without even seeing the rock???
Thanks in advance
