I have experimented a lot on how to deal with those pesky fine chains that snarl and tangle in a jewelry box. This is the best way I have found so far. You need large straws, so the lobster claw and jump rings fit into it. Then a little snip in the end of the straw holds the end of necklace just to keep it from sliding down inside. Even if the chain comes out the bottom for a few inches so far they haven't tangled in the bottom of the vase.
