Yes, you can use truSpace for modelling things like jewelry. It really depends on what version of tS you use as to how Poser compatible is. You'll either love or hate the interface. I hate it. Hate it, hate it, hate it. OTOH, PhilC gets wonderful results from it. LW and tS have demos, so you can play with them before you make a decision. I really think LW is the better choice between those two.
