Tiamat
Tiamat asked Andrew Rowe:

What would be the best way for Croin or another enchanter like to reverse engineer an enchantment like the jade box or a sword like Selys-Laynn? Also is it possible for a strong enchanter like Professor Vellum to create something like the jaden box without using runes like Wyrnn Jaden?

Andrew Rowe This is a really good question, but it's going to be discussed directly in AA4, so I'm not going to go into too much detail here.

In brief summary, though, even if the item is foreign in origin, someone can theoretically figure out how each individual component part works and then work on duplicating those components. It may not work identically, but the core functionality can potentially be replicated.
