This nerdy necklace features the value of an electron's radius in green aventurine beads. It's the perfect gift for quantum physics nerds, teachers, students, and graduates! You can find more information about how I include numbers in my jewelry by visiting this page on my blog:


I used the 2010 CODATA value for the electron radius, measured in meters: 2.8179403267 x 10^-15 m. This value has since been updated; the necklace is three years old. It measures about 18" from end to end, or standard "princess" length.
