Vintage & very lovely clear & purple rhinestone necklace & earrings set in box

Vintage and very lovely clear & purple rhinestone necklace and earrings set in box. Necklace is approximately 18 1/2 inches long. The earrings are 2 inches. This is a gorgeous and very colorful se with a nice, vintage patina. Looks like it has never been worn. The tag near the clasp has a maker's mark, but I can't identify it. Thanks for looking and please make an offer on anything. All good offers will be gladly accepted. 😊
