(See related question here.)
I was given a necklace with a cute geode pendant. Love the color, but it doesn't fit me well -- I don't like the length it hangs at, and I don't like that the stone is horizontal instead of vertical.
It's a fairly thin silver chain, connected to a couple of loops which connect to embedded rings in the rock itself.
What can I do to make this longer? Do I need to replace the full chain (somehow) or can I extend what I've got?
