This question just made me laugh! My jewelry is a mess. Most recently worn is "stored" in a pile on a dresser. Bakelite bangles are all on bracelet racks by color. Although, sometimes just in a pile on the dining room table. I have one of those standing mirrors that open on each side to store jewelry. A brilliant idea, for necklaces that can dangle, and earrings. Unfortunately, I haven't figured out using the opposite side mirror, and not much is in there except pieces I have forgotten I own. Maybe some broken bits, too. Possibly things I might sell? Rings are in a ring dish. There is ring storage in the mirror, but I can't remember to use it. So, dish on the bureau for rings! And I also keep a special antique Uranium glass ring inside an antique art nouveau ring box given to me by
@carla rey , in our VFG Secret Santa, this past year. Brooches are mostly in pockets inside the mirror. Hat pins are currently atop the dresser, for further evaluation and decision of keep or sell.
Pieces that might be for sale are in a box in my office. Pieces that are already listed for sale are properly stored in their shipping boxes, in a section of my basement where all listed items are kept. I have several vintage jewelry boxes that I use for display, when I do an in-person sales event. Those are filled with lower price point pieces and chatchkis - I love to be able to give children a small shiny object when they are drawn to my booth. The older boxes are lined in lovely velvet, and those are really nice for storage on a dresser, doubling as a display.
Probably the most important storage tip I can recommend is storing beaded, strung jewelry flat, as to not wear the thread further. I have a huge pile going to my jewelry fixer friend for re-stringing. The necklaces on chains or wires I hang on a necklace display (and within the jewelry cabinet/mirror). If you have a large collection and also need a standing mirror, I really recommend getting one of those thingies. I wish I could remember to use it! I also have a firm belief of out-of-sight, out-of-mind. Which may be the reason I ended up with so much bakelite - when I couldn't see my collection.
Don't store different types of plastic together. I also recommend not wearing different types of plastic at one time. Bakelite is much denser than others, and may cause breaks or cracks (especially in older, more dainty celluloid). The other reason to keep separate, is in the horrible instance that you may introduce a plastic degradation disease to your collection, it can spread to any other plastics. (It smells like vinegar, commonly occurs in old dolls and lucite purses, enhanced by sunlight.)
Pearls should be stored separately, maybe in a little cloth bag. If any metals have verdigris, keep that separate (if you are keeping the piece and not tossing), that can spread. Oxidization can be managed with polishing. Verdigris is not curable. I wouldn't necessarily toss it, depending if the piece is nice, old, sentimental, etc. Just be careful of it not contaminating other metal jewelry. Just like when I bring clothing into my house, either to sell or keep, I have a process for cleaning and storing so I don't cause harm to mine or my partner's collections - jewelry has those needs, too.
I probably answered all of the questions you did not ask, and none that you did. Just some things to think about!
