Lil Bee’s Bohemian Stone Loop Earrings- 664 $25 or $20 w/offer

These Lil Bee’s Bohemian stone loop earrings are quite unique. The stones are real but I am not sure what they are, any ideas? I would like to say turquoise but there are white spots on the stones which you would not see on the stone. The metal has been tested and appears to be sterling silver.
