Ringly connects to your smartphone through Bluetooth and either vibrates or lights up when you get a notification. You can even customize how you receive the notification by changing up the vibration and light patterns.
"We were going for something that was simple, classic, something that a lot of women could get behind," Ringly cofounder Christina Mercando said to Business Insider when the product launched in June. "It's so small and discreet that people wouldn't know the technology is there."
The ring is made of 18K-matte gold and comes with four different gem stones: black onyx, pink sapphire, rainbow moonstone, and emerald. There's even a limited edition "Dive Bar" ring, made out of tourmalated quartz in a rhodium plated setting.
