Hi, Samantha….I deal with this issue all the time when I travel.
What I do (and I realize this may not work for you) is I put all the valuable jewelry (that means grandma’s cameo) in small zippy cloth makeup bags you can get at the five and dime. Some of these are cloth pouches that hold pencils/pens for school——which are often a lot less expensive than makeup bags and work just as well. They are a good size. I wrap the jewelry in tissue first and then put them in the zipper pouches. Then, I put those small pouches in a larger makeup bag and put it in my carry-on. I always do that. I get all my non-valuable and stuff that could be replaced and put that in the same small bags and stick them as far in the middle and bottom of my regular suitcase. (That would be only if your carry on is getting loaded with things that are not valuable and you won’t worry if they get lost.)
QVC sells some superb, superb, jewelry rolls and bags. Just go to QVC and search for “Prezerve” (with a z). You can watch the video demos and see how much stuff you can cram into one or two of those bags….it’s amazing. I just bought one but have yet to try it on a trip. I usually do the above.
You can get small specialty jewelry plastic bags with a zip lock on them on ebay, too. If you get the heavy duty ones, you can stick brooches in them and they will not puncture the plastic.
Good luck on your trip!
