I arrange mine by silver, gold, bracelets, necklaces, brooches. Earrings can be sorted by color or just in one area. An easy way to hang necklaces (costume jewelry) is to put up a flat hook on the wall in an inconspicuous place and hang your chains and necklaces on that.
I painted a cool- shaped board I got at the Goodwill, (I had to use the back because there was a word-burned saying on the front), then bought a bunch of knobs I got at Hobby Lobby and screwed them in.
I have trays with small compartments in a drawer and keep them separate from each other.
I have all my necklaces hanging on the wall in my closet. You can use hooks and knobs to hang them. Here is mine https://www.homeroad.net/2019/02/walk-in-closet-jewelry-organization.html
