I travel with my jewelry in a case that I throw into my carryon. I've never had a problem and there is usually one or two pieces from J.Crew (including more recently my gray crystal brooch necklace which is on the heavier side compared to some of my pieces). Hope that helps! I had no issues with security.
Thks for info. I have friends who put jewelry in their suitcases, and check them! Never! It kills me to check my makeup (I buy mini sizes and leave the LeMer home!)
