Ltd Edition Coal Bangle with 8 Diamonds San Francisco

San Francisco Coal Bangles with Eight Diamonds are made using the serial number from illegal guns and metal from shell casings either swept from crime scenes or turned over during gun buyback and amnesty programs in Pittsburg, CA.  % of the net proceeds from each purchase are donated back to Pittsburg, CA to get more illegal guns off the streets.

Caliber Collection Diamond pieces are non-refundable.


  • There is powerful double meaning behind the name The Caliber Collection®. The first is the caliber of a gun. The second is how the caliber of a city is raised when illegal guns are taken off its streets. The oval shape of the bracelet mimics the trigger cage of a gun and serves as a reminder of the destruction that is caused when the trigger of a gun is pulled. Each series carries a serial number that corresponds with one of the guns that has been voluntarily turned in by an individual to the Pittsburg, CA Police Department on March 16th, 2013 during a privately funded Gun buyback and amnesty program. Embedded in 8 places on the side of the bangle are diamonds (approx 0.11cts each); strong, precious and rare…like human life. This special limited edition finish is inspired by the extensive history of coal mining and industrial development since the late 1800's in Pittsburg, CA. The side of the bracelet is hand hammered to symbolize the hard work required, not only of the police, but of each individual, in the fight to get illegal guns off the streets of their community. The diamonds used in all pieces of the Caliber Collection® are conflict free diamonds.
