Turquoise or Chrysocolla - can't decide

Gotta show off these earrings that I just picked up. Beautiful stones - pics don’t do em justice. The stones are an ocean blue/green. One picture has too much light and the blue/greens don’t show up. Turquoise vs Chrysocolla? Backs are marked with a “K”, “Sterling”, and “Santa Fe”. Wondering if they were a custom design from James Kallas shop. So what do I have guys?
