Wearables didn’t exactly close out 2016 with a bang. According to an IDC report, the sector only grew 3.1 percent year-over-year in Q3 of 2016. While that statistic, along with reports of wearable companies’ struggles (Fitbit recently laid off six percent of its workforce) may signal a problem for the sector, Warren Buffett is actually embracing wearables. The billionaire investor, who has been cautious about investing in the tech sector in the past, is diving into wearables with a new smart jewelry line produced by his company Berkshire Hathaway’s jewelry subsidiary Richline Group.

The line, dubbed Ela, will debut this spring, starting with smart wristwear—but don’t expect to see a smartwatch from the get-go. According to a report from ZDNet, Ela has been working on elegantly designed smart bracelets and plans to extend into other product categories, including rings and earrings, in the future. Ela devices will connect to both Android and iOS devices and share activity data with Apple’s HealthKit and Google Fit, although the specific activity sensors that each device will have are unknown. Ela devices will also receive smartphone notifications, and the user can set gems on the device to glow in different colors and vibrate depending on the alert they’re receiving.

Cliff Ulrich, product innovation manager for the Richline Group, told ZDNet that a goal was to create devices that are more than just “prettier step trackers.” Ela devices will also have their own mobile app with which users can create “memories” that can be shared with a specific device. Content like photos, voice recordings, and songs can be preloaded to Ela devices so that users who are given the device as a gift can open up the content on their smartphones and relive “special memories” they have with the gifter.
