"Jewelry Webguard™
Consumer protection has long been a high priority in the jewelry industry, and the growth of Internet trading offers new challenges. EGL USA's unique Jewelry Webguard™ service protects consumers as well as gem dealers in their online transactions.
When you buy a certified stone online, ask the seller to ship it with the certificate to the nearest EGL USA office. Our lab will provide a third-party endorsement that the stone and its certificate match and will issue a Jewelry Webguard™ certificate. EGL USA then ships the stone, its original certificate and the new Jewelry Webguard™ certificate to you, the buyer.
Some insurance companies will not cover shipping between a dealer and a consumer without a third-party endorsement. The Jewelry Webguard™ service protects both parties in the transaction."
Or maybe the community is so small and the well-knowns are so prominent, perhaps Messrs. Norris, Rankin or Ms. Hendrickson would be willing to inspect/broker. (Ok, maybe not broker. You have to negotiate your own price, but maybe they would be willing to authenticate). Most law firms do this sort of transaction as well; you have to provide your own expert though.
