Good to know

For BIG Certificate services, we only accept loose, unmounted diamonds and gemstones.

To use our services, clients are kindly asked to download the necessary documentation, and send i tus together with the goods. As is our policy, we contact our clients on receipt of goods to confirm both their arrival and the order.

In general, we usually require five working days to complete the testing. This does, however, depend on the workload. We contact clients if it seems likely that more than the standard five working days will be required to perform all the analyses. However you can ask for express services which take one or two days.

Clients are asked to read our General Terms and Conditions, which form an integral part of our order form.
