Vintage black stone/silver large clip earrings

Vintage semi-precious large black stone clip earrings by Alex Nicole on original card. Price back when was $40. Could be onyx, or Jett black but not sure--from my Aunt's estate. Stone and silver not polished because some like it not so shiny. They are 2" long and 1 1/4" wide. If you love large earrings, you'll love these.
