My sister bought me this bracelet from a monastery in Serbia. I've been searching for quite some time to find which Saint is depicted to no avail. It looks like St. John Chrysostom but I'm not sure.
It is almost certainly John Chrysostom. Compare your image with the middle figure of this icon of the Three Hierarchs
The middle figure is labeled Chrysostom. To the left of him is Basil the Great. To the right is Gregory the Theologian.
Required, but never shown
