The Ringly ring is 18 karat gold plated and contains a semi-precious stone. What makes Ringly special is that it connects to your phone via Bluetooth LE and sends you notifications through vibration and light whenever you receive a text, call or email.
This notifications can be customised with the Ringly app (available for iOS and Android). The app can also sync with other apps that offer push notification, such as Instagram, Facebook, Twitter, etc.
Ringly will be available in three sizes (6, 7 and 8). Ringly is available in black onyx, rainbow moonstone, pink sapphire, and emerald stone and for a limited time only will cost $145 rather than $195.
