I’d suggest contacting Jewelers Security Alliance for their hints on
security in transit. Their Web site is http://jsa.polygon.net. You’ll
have to register with Polygon, since the site is restricted to the
trade, but I don’t believe there is any charge for that.
Be sure to check out the Crime Prevention Bulletins, which include
pieces specifically geared to traveling jewelry salespersons and
shipping jewelry safely. JSA also sells a 152 page manual on security
issues, which might be helpful.
JSA does a great service to the jewelry industry in educating
jewelers about security and in working with police and the FBI to
catch criminals. They conduct regular seminars on security, and they
also send out regular “wanted” notices to members letting them know
about criminal activity, which has helped catch quite a number of
robbers. They’re a worthy group to support with membership.
