W Germany Filigree Art Glass Earrings

I labeled these as ‘Art Glass” but there are other semi precious or precious gems they could possibly be - ie moonstone, jadeite, or Jade. Marked W Germany filgree clip earrings with centre green cabochon, green rhinestones and miniature pearl. Gold-tone setting but I do not know the gold colour is plated or silver. Measures 1 inch tall. Every good vintage condition. Stamped W Germany. These are very rare.
