Pluto

Pluto would like to remind you that it doesn't matter if you get knocked down - or say demoted from a full-sized planet to one of five dwarf planets - it's how you bounce.  

Beautiful detailing. Sterling silver. Metal mark inside. Size 7 or just slightly below.

Would be extremely content to encircle the digit of your choice. 

Would not consider it a demotion. Besides, has eyes on the galaxy.
