Hey Simon
Glad to hear from you. Before you head out into the boonies (if it is safe to assume Naypyidaw is not already the boonies?) you should make sure you have the following three items in your kit bag:
- A jeweler’s loupe
- Digital scales
- Density pen
Even if you don’t know how to use them yet, anyone selling stones should take you very seriously when you pull those items out of your bag. 🙂
Best of luck with your new job.
