Vintage GIVENCHY Earrings Necklace Set Apprx Circa Late 1980’s Crystals Rare

Vintage Givenchy necklace and earrings set from approximately 1980s or early 90s. This is from my personal collection. I have had this set for over 30 years. I believe the stones are crystal and it looks like malachite, but I can’t be certain. They may just be synthetic stones. I always thought these looked like little Christmas trees and enjoyed wearing them around the holidays. All three pieces are marked GIVENCHY. excellent condition. Only very minimal age-appropriate wear to metal
