The90 Unveils $300 Gem Necklace That Tracks UVA and UVB Exposure

Summary
The90 launched The Gem, a pendant-style wearable that measures real-time UVA and UVB exposure and is now on sale for $200 ahead of a planned $300 price.
Sensors in the necklace track changing UV levels throughout the day—including outdoors and near sunny windows—and send the data to an app.
That app builds a personalized skin profile and delivers guidance such as UV thresholds, sunscreen reminders and recommended sunlight-exposure windows.
Founder Stacy Salvi, a former Fitbit executive who spent eight years at the company before and after Google’s 2021 acquisition, is positioning The Gem as a new jewelry-based wearable category.
