On May 10, 2024, a CME slammed into Earth's magnetic field, sparking the biggest geomagnetic storm in 35 years. Moments later, the students of Earth to Sky Calculus launched a cosmic ray balloon directly into the storm. This premium Tahitian black pearl went along for the ride.
 
During the storm, the pearl floated through the stratosphere for 3 hours while sensors inside the payload collected radiation data for the students' monitoring program. Later, when the sun set and the sky grew dark, red and green auroras danced above the Sierra Nevada mountains of California where the balloon was launched.
 
This is a premium 5-star quality pearl measuring 9mm in diameter. It is mounted inside a sterling silver heart outlined by glittering cubic zirconia nuggets. The pearl comes with a greeting card showing the necklace in flight and telling the story of its journey to the stratosphere and back. This is truly a once-in-a-lifetime gift.
