Het ontstaan
The concept originated in 1969 as a keyring promotion: buyers of certain Tiffany pieces received a keyring with a round tag and the address of the New York branch. Anyone who lost the keyring could — hence the text — send it back; the house identified the owner by a unique number and returned the pendant. The promotion became popular enough to be included in the assortment as a follow-up product.
In the 1980s, the idea evolved into a full-fledged jewellery line: pendants, rings, bracelets, and earrings with similar tags in round and heart shapes. From the 1990s, it became one of the house's best-selling sub-lines worldwide, reaching a customer group that the house had not previously served daily.
For the second-hand market, this is a dual movement: enormous availability keeps prices relatively low, while brand recognition simultaneously maintains consistent demand. The line is thus liquid but not growth-driven; it is an entry-level category that rarely rises high in the collector's market but also rarely falls far.
