Very Pretty 925 Silver Turquoise Colour & Black Stone Bead Dangle Earrings

Beads measure approximately 8 mm and 6 mm and I’m assuming they are natural stone beads. I have another pair listed that are a violet blue colour and they register as Tanzanite or Quartz on my gem tester. These earring beads register in the glass zone and just on the border but under magnification they look like natural stones. ☀️Bundle items from my closet to save on shipping & get a 25% discount☀️
