from the letter, this phrase:

"Solve et Coagulum": Separate and Join Together (or "dissolve and coagulate" in Latin) is a medieval alchemy quote, which is to say that nothing new can be built if not before we make space, breaking the old. ... Solve et Coagula is the essential alchemical process.

Any guess as to what kind of ring this is?

Here's somewhere else you can find the 'solve et coagulum' inscription. Check out the arms.
