"dipped" bezel?

[kraftrourke]

I have come across quite a few organic "liquid" or "gold-dipped" bezels perfectly-formed around irregular shaped or unfinished druzy quartz. some of them are very inexpensive and seem mass produced and some are very expensive and are called "hand-dipped" in sellers descriptions. There is also another form of bezel that looks like it's melting up and over the stone, holding it in place. My question is simply, what are these processes actually called? I'd love to research about them or know what to look for in a class...


two different examples.

Thanks!
