Tiffany’s keys collection has been enormously popular with fans of all ages and budgets. The company recently introduced a heart design (just in time for you know what) they say is inspired by archival designs. Set with diamonds and set in 18k gold, it also has Tiffany spelled out on the back (not sure I’m wild about this element but at least you won’t really see it). Available for USD $6,500, and also on offer in other mixes of gold and stones.
