Is it gauche to wear more than one ring on a hand? And once I have rings on the ring finger, what’s next? Are there any ring etiquette rules? How do I make it not look tacky? — Beth, Brooklyn, N.Y.

When Ariana Greenblatt, the 16-year-old “Barbie” actress, made her red carpet debut at the Golden Globes this month, she did so in a plain white Saint Laurent tuxedo shirt, black trousers, a black cummerbund and about eight Chopard diamond rings, one on nearly every finger, which she proudly fluttered at the watching paparazzi. And she wasn’t the only attendee so adorned.

The jewelry designer Irene Neuwirth, also at the Globes, stacked up seven of her pearl rings on both hands to go with her white Christy Rilling dress. “There’s something a little lawless about wearing a lot of rings,” she said when I asked.

Other ring aficionados include Johnny Depp, the former Gucci designer Alessandro Michele and the Dior designer Maria Grazia Chiuri, all of whom like to load on the finger jewelry, and all of whom underscore the point that there are no actual rules when it comes to how many rings you can wear at once or on what fingers you should wear them.

Even the idea that you have to wear an engagement ring on your left ring finger is more convention than actual diktat. The ancient Romans believed that that finger contained a vein, the vena amoris, that connected directly to your heart.

Still, there are certain considerations that should be taken into account when dressing your hands. Our hands play key roles in how we interface with the world, and what we put on them matters.

On the one hand, said Rachel Garrahan, the project curator of jewelry at the Victoria and Albert Museum, “the pleasure of wearing a ring, unlike other forms of jewelry, is that the wearer gets to enjoy it as much as everyone else.” Just look down at your hand when you want a shot of joy, or a boost of confidence, she said. And if one ring does that, imagine what two (or three or four) could do.
