A $249 UV-tracking necklace warned a wearer of high ultraviolet exposure only after heat exhaustion had already set in during a 90-degree Los Angeles outdoor gathering.
Heat and Ultraviolet Exposure Under the Patio Umbrella
With temperatures rising to the 90s in Los Angeles, avoiding the heat wasn’t exactly an option while attending a relative’s outdoor party in August. Sitting beneath a patio umbrella with a powerful fan nearby gave a false sense of security, assuming protection from both the sun and heat. Half an hour later, exhaustion, dizziness, nausea, and generally unwell symptoms set in—manifestations consistent with heat exhaustion.
Around that same time, a notification arrived from an app paired with a $249 UV-tracking necklace called Gem, manufactured by a company called The90. The device, which was priced at $149 at the time of publication, warned that UV exposure had climbed considerably.
Pricing, Hardware Details, and Verification Status
The hardware and associated software details stem from November 08, 2026 reporting. The Gem necklace carries a standard price tag of $249, though it was available for $149 at the time of publication.
Verification status for broader feature sets and underlying sensor specifications remains mixed. Authoritative specifications and documentation confirm the pricing and core tracking functions detailed in industry reports. However, other performance metrics and long-term health monitoring capabilities remain unconfirmed.

What Tech Consumers and Gadget Buyers Should Watch Next
Tech consumers, gadget buyers, and developers tracking wearable health technology should monitor how ambient temperature warnings integrate with ultraviolet tracking devices. Because shade and fans do not mitigate all forms of heat and radiation stress, users must watch for updates regarding how real-time alerts handle simultaneous heat and UV spikes. Additional industry reports and verified documentation will clarify whether future iterations can address the gap between environmental symptom onset and app-based notifications.
