You don’t ever have to tell anybody you’re wearing a vibrator to dinner. But if you want to, you can now flaunt it.

Vibrators and other sex toys for women have in recent years veered away from straightforward penis-shaped apparatuses and toward more creative and ambiguous designs. But now a growing number of innovators are driving a particularly bold revolution: sex toys, and vibrators in particular, as jewelry.

Sex-toy subscription box startup Unbound started selling accessories that double as sexual stimulation — like nipple clamps you can also wear as earrings — in 2016. Now, it’s going a step further with the just-released Palma ring that sells for $128. It comes in silver or gold, looks like a pretty standard metal statement ring you might buy at a stylish but inexpensive shop, and is also a three-speed vibrator. It took two years to develop due to having to fit the circuit board of a vibrator into a ring a person could comfortably wear.

The gold standard in this genre is Crave’s Vesper, a $69 necklace that looks like a minimalist shaft in silver or gold — but is actually a high-powered sex toy. At first glance, there’s something titillating in the fact that it doesn’t really look like a vibrator unless you know it is. Screaming O’s vibrating thongs — which cost $25 — are controlled by a ring you wear on your finger.
