Maybe because I do not have many finished jewelry ;)
That’s why I am more into storing stones and beads.
Storing stones and beads is not difficult. I mostly use plastic containers like these here.
As for finished jewelry, people says it is an art in itself. Some use wine glasses to hang earrings, twist wires to make wire trees to hang necklaces and earrings (ehm! planning to do this), modify old picture frames into jewelry frames, and many many more ways depending on your creativity and of course budget and space.
Mine is quite simple here and rather "artless". I simply throw everything into this individual compartment here ;-)
This way, I can just choose which one to put on when I change my clothes...for convenient sake.
