NWOT Light Green Stone Crystal Disc Necklace & Earrings Set

Never worn, New Without Tags (NWOT) matching necklace and earrings set. Unknown light to pale green stone/crystal ranging from light to darker, in flat discs, create this necklace and earring set. Earrings are lever back style. I am unsure if these stones are Adventurine, Green Calcite, Chrysophase, Green Jasper, or something else entirely. (If you have any ideas, please let me know!) Please see photos for details.
