The most beautiful clouds on Earth are located in the stratosphere: Polar Stratospheric Clouds. Their extraordinary colors inspired this authentic Swarovski pendant--and it has been to the stratosphere! On Nov. 2, 2019, it hitched a ride 109,580 feet high on board an Earth to Sky Calculus cosmic ray balloon.
 
After the balloon exploded (as planned), the payload parachuted back to Earth, landing in Saline Valley on the verge of Death Valley National Park. The pendant had a wild ride, and the students got great data for their atmospheric radiation monitoring program.
 
The students are selling these pendants to support their cosmic ray ballooning program. The glittering heart-shaped crystal is wrapped in a silver-embossed infinity clasp, symbolizing unending love. Each one comes with a romantic card showing the pendant in flight and telling the story of its journey to the edge of space and back again.
