I had a pair of amethyst earrings stolen that I left in a drawer once (lesson learned - they had more sentimental value than intrinsic value), but never had anything stolen since I put everything with even minimal value in the wall safe.
Generally, even what I put in the safe wouldn't be worth very much. I put a small bit of backup cash and my travel documents and some old electronics in there as well as a bit of inexpensive jewellery. The sort of stuff that if left out in plain sight might be a temptation to someone and a hassle or inconvenience for me to replace.
I never travel with jewellery or anything of any appreciable value these days. Basically, I travel with cheap or worn out and/or old everything. Gone are the days when I would dress up and bring nice things with me on a vacation. I enjoy those at home. I bring an outdated ipad and old iphone for travel. Nothing that I have that has any real value goes with when I travel. I have lost a few nice items that way. Never again.
