Vintage Signed "Mark" Necklace w/ Crackle Lucite and Glass Facets, Beautiful!

This one is a stunner. The light smoky lavender crackle finish lucite and bits of hematite-like faceted glass make for an alluring combo. Signature is "mark." which I've learned is a line sold by Avon. I've included plenty of pics to show its beauty closeup as well as further out. As with any vintage costume jewelry, please be aware there can be patina and imperfections of plating, as well as wear on portions of the piece. I try to bring anything out of the ordinary to your attention when I can. But reviewing the pictures and asking questions ahead is the best way to be aware before purchasing. All sales final. Thank you for shopping my closet!
