How can I submit a stone by mail?

You can ship stones into the lab for reports using your preferred shipping agent.

The most cost effective method of shipment depends on the value of the goods and can vary by location. The following are general guidelines. For exact shipping rates, contact your preferred shipping agent.

Ship with UPS or FedEx

For items of moderate value (~US$10,000) many of our clients have found UPS, FedEx, or their local post services to be the most cost effective.

Please note that goods shipped in this way will be subject to 7% VAT on the declared value of the items.

Ship with Ferrari, Malca Amit, or Brinks

For higher value parcels (~US$10,000+), it is often more cost effective to ship with a specialty shipping company such as Ferrari, Malca Amit, or Brinks.

They have services that can bring the goods in for testing only and avoid paying the usual 7% VAT, as long as the items are shipped back out again. Because of their relatively higher service fees, this option is usually more cost effective for more valuable parcels.
