Now its flagship store operates in Midtown Manhattan and sells things like $4,000 rings that spell the word “love” in small diamonds and $165,000 gemstone necklaces. (One $2.475 million engagement ring weighs as much as a bullet.) And for decades, it was inside a 10-story fortress on Fifth Avenue.

Last weekend, Tiffany had to empty that store for a long-planned renovation.

But first, it had to relocate its valuable merchandise to a temporary location a few steps away. Cue the security.

The company assigned 30 security officers to oversee the transfer. New York City police officers stood outside. A tent was erected outside the temporary store’s entrance.

The company kept a lookout for any unusual mentions online, and employees were told not to post messages about or photographs of the move on social media, my colleague James Barron reported.
