The golden ball is her treasure. All dragons want treasure, wether it's golden coins, a man, a daughter or something with emotional value. A Ryu likely has a golden ball till the point of obtaining a husband. She then passes her ball onto her daughter as a heritance like object to symbolize caring for something precious in one's life.

(Reptile's answer is way more likely, I just imagine the ball fulfills both the function Reptile described and this one. ^)
