(Bloomberg) -- Down with love? Only about half of Americans will celebrate Valentine’s Day this week, according to data from the National Retail Federation. (It was 60 percent ten years ago.) But, in a twist, the organization expects more than $20 billion worth of gifts to be purchased this year, as the ones who do celebrate the holiday are spending more.

Even those who say they aren’t officially “celebrating” plan to do something, and this is doubly true for millennials. More than a third of those under the age of 35 who are opting out of the day’s romantic agenda say they still have plans to buy something special for themselves.

In that case, consider one of these 14 gifts that fall under the category of “old dogs, new tricks.” They’re all classics, so you know they’ll stand the test of time whether you’re buying for a significant other or just looking for a reason to celebrate yourself.  But they’ve also been tweaked just enough—a new color, different size, exotic material—to appeal to a new generation that may have different ideas about how to say I love you.

Cufflinks from David Yurman have previously used exotic materials such as from meteorites.

This new addition to the Tiffany T True collection riffs on the design of the brand’s popular cuffs and suggests a subtler approach to its prominent “T” design. These Tiffany T True bracelets are available in 18-carat gold and 18-carat rose gold. $4,800; available online
