A new smart jewelry pendant aims to make sun safety personal, wearable, and stylish.
The90, a company founded by former Fitbit employee Stacy Salvi, has announced The Gem, a smart jewelry pendant necklace that measures real-time UVA and UVB exposure.
Key Details
- The Gem is a round necklace pendant containing sensors for UVA and UVB rays.
- Data is sent to a companion app that creates a personalized skin profile with UV thresholds, sunscreen reminders, and sunlight exposure windows.
- The product is currently available for $200, with a planned retail price of $300.
Context
The company positions The Gem as a new category of wearable. Other UV sensor products exist from startups like Shade and established companies like L'Oreal, but The Gem is designed specifically as a pendant necklace, focusing on form as much as function.
