The LEGO bricks were each hand cast using the lost wax method. An actual LEGO brick is burned out for every piece destroying the original. 1 plastic brick = 1 silver brick. Made from recycled, locally sourced sterling silver, this LEGOesque building block necklace is the perfect addition to your unique jewelry collection! The coolest thing about this building block is that it still works! Attach a cache of your favorite colored LEGO blocks and define your daily mood. Made in Portland, OR USA.
