Help to identify the symbol on this gold mesh bracelet center and possible value

This was found in my mother's jewelry from 40-50 years ago.

The center piece opens to adjust the length of the gold mesh bracelet. There is a small stone in the center of a star surrounded with tiny white beads. This center piece is attached to a gold oval with tiny crowns.

I would like to know if the center symbol has any significance ? Do you have any idea what the bracelet might be worth?
