Šipkica za pupak s grupom raznobojnih kamenčića

This surgical steel belly ring features a 5 mm ball at the top and a cluster of different colored prong-set crystals in complementary colors at the bottom. 
This piece is externally threaded, meaning that to secure it in place you simply need to pass the bar through your piercing and screw on the top ball. 
The bottom piece measures 12 mm high by 12 mm wide.
