Is it OK to Redesign Parts of Thrift Store Jewelry to Sell in Re-made Jewelry?

By Marina.

If jewelry is purchased at a thrift store, can parts of it be reused to create a different piece and sold?

I understand being respectful of a designer’s name of their jewelry or clothes but what are the rules?

I see the same type of bead bracelets with pennies and other vintage coins attached, so how is this not unethical?

Kudos to the creative people out there I am one of them!

Thank you.
