It's our most beautiful space pendant ever: The Sterling Silver Opal. On Sept. 5, 2021, the students of Earth to Sky Calculus launched one to the stratosphere onboard a cosmic ray research balloon. At the apex of the flight, it floated 103,018 ft high, above 99.7% of Earth's atmosphere.
Opals are cousins of moonstones; in fact they look the same in low light. But when bright sunlight strikes an opal, something special happens. A spray of color emerges from the stone. Indeed, this happened while the stone was in the stratosphere.
Wrapped in a sterling silver Celtic love knot, the opal is suspended from a matching 18-inch chain with a 2-inch extender. Each pendant comes with a greeting card showing the opal in flight, telling the story of its trip to the edge of space and back again.
All sales support the student's cosmic ray research program.
