Hooray for your upcoming trip, @Janelle! That’s so exciting you’ll have an adventure and see your family again after all these years
I personally wear my crystal jewlery- in addition to being very portable, crystals don’t set off the alarms at airport security and raise no questions. They offer all the benefits and security of home without drawing attention and not taking up much suitcase space (or any space if you wear them on the plane!)

Good luck and safe travels, Janelle!
