This is a shiny ball or marble from my tutorial title names " How to Create a Shiny Ball in Illustrator" To make it in above CS3 was easier  than doing this kind of effect from older version of Illustrator.

Do you see water drops on the peach? I also made it vector art. Actually you can pick this water drop from vector peach which I uploaded to Fruit category before. I just pick it out for you.

I downloaded this vector book from somewhere. Thank you for anyone who shared this on internet. Next time I will create this by my own.
