Jesse's Ring of Luck

A ring that holds a yellow gem that is filled with Felix Felicis, the ring is described as when wearing the ring, the wearer will gain a large amount of luck and good fortune if they activate one of the shots in the gem. The ring was given to her by Jennifer Bates after hearing that she was accepted as an Auror and wanted to give her a little something to celebrate and to protect her on her dangerous missions.

So far the most the gem can hold is about 3-4 usages of liquid luck before needed to be refilled.
