This repetitive design appears to be an orange blossom with a beaded edge. The effect is one of quiet refinement.
This is an opulent styled pendant of multi colors that basically is dark red, yellow/gold and brown with some blues and rhinestones added for decoration. With a solid color, this would be a smashing fashion accessory. The colors are rich, opulent and yet not just jumping up in your face. The condition is excellent, the earrings are screw backs and ready to wear, and there is some minor wear to the surface of the clasp and back of the earrings, but while prowling through Grandmothers jewel box, you found this, and did not want to change anything about it.
