Vintage Gemstone Earrings 18k gold plated David Aubrey Carnelian Orange Green

Vintage Gemstone Earrings 18k gold plated David Aubrey Carnelian Orange Green Black 2000s David Aubrey jewelry was established in 1996, but I do not know exactly when these earrings were designed. The orange 🍊 faceted beads are Carnelian, and have distinctive agate stripes in the sun so I am confident in identifying them. The green stones may be Jade or Aventurine. The black stones may be Onyx, or Black Tourmaline. These have a beautiful classic look that would be lovely for semi-formal or formal looks. They are in excellent vintage condition. Measures approx 2.25” x 1.25” Thanks
