If you think you have been seeing more men wearing rings, bracelets and pendants — like Jay-Z, John Mayer or Hiroshi Fujiwara, known as the Godfather of Tokyo’s trendy Harajuku area — you’re not wrong.

The trend, which began several years ago along with the birth of men’s wear fashion weeks, has firmly taken hold around the globe. (The men’s weeks, however, haven’t enjoyed quite as much success.)

Some industry figures say Instagram has had a lot to do with the appeal.

Men today “don’t look at fashion magazines, but they look at Instagram,” said Cynthia Sakai, a Japanese jeweler who designs her Vita Fede line in New York, has it made in Italy, and sells it around the world in fashion-forward stores like Harvey Nichols and Lane Crawford. She is introducing a men’s line this fall. “Guys do style posts on Instagram, they do selfies and tell their friends what they’re wearing. Instagram and Snapchat changed the game.”
