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 set is a fabulous gift for your bestie or lover. The 2X2 Building Block pendants (with tab) that have been created to fit together. When stacked, these pendants form a sweet little heart. One to keep and one to give! The pendants measure approximately one inch long and are 5/8 inch wide. They each hang from a 16 inch sterling chain. The pieces have a black patina which is then brushed back to better hightlight the "studs". Handmade in Portland, OR USA.
