This necklace is so precious! I designed the pendant on my computer and laser cut it from 1/8" frosted acrylic. It hangs from a 16" silver chain with a 3" extender. The pendant is approximately 4 inches by 1 1/4 inch. The necklaces are sturdy but you should still be a little bit careful with them... just don't throw them into the bottom of your purse!
