New vintage dangling crystal earrings

New vintage dangling crystal earrings clip on Quick list One line of 8 crystals end in 3 lines of 4 crystals each. Trio theme in this collection. Noticed a few pieces in this collection have odd black crystals thrown in seemingly randomly. One has 4 black crystals on the bottom “tassels “. One has 3 black crystals grouped together on the bottom tassels. All brilliantly catch the light and give a lot of rainbow refraction! New vintage c. 1970s-1980s. By Artistic Jewellery Canada. Costume gold or gold plate. The original packaging does not say it is crystal or Austrian crystal.
