The below product has been seen and where possible graded by Joseph Mackley, Senior Gemologist and Appraiser of Mackley & Company, Knoxille, Tennessee. You can depend on our opinion. Any item you are interested in, you are dealing with the owner or their representative. We have coached each to make sure they receive good funds before sending the product out. If you wish Mackley and Company to be an escrow service where we make sure we have the product, receive your check, then send the product when the funds clear, then we would be happy to do so. You just need to request that service with the seller and get their OK.
