Items such as rings and earrings are very small and easily lost.
A lot of jewelry is delicate and easily broken so one needs to think about how to pack these small treasures.
I never put my jewelry in bags that will be checked. Its just not worth the risk, and it really doesn't take up much room.
I find that the best way to pack my jewelry is in a small travel sized box designed for that purpose.
There are a lot of beautiful options in the stores and these are some of my favorites...
This beautiful blue box comes from Pickett in London. They are one of my favorite stores and do ship outside of the UK.
I also like this Jewelry roll from Tiffany, but it doesn't have enough room for me.
