UNIQUE Sterling Native-Style Adjustable Ring (White Turquoise or Howlite)

This ring is seriously amazing. I have never found another like it. This was sold to me as White Turquoise and Onyx, but it could be Howlite and Spinel. I'm not a gem expert, just a suspicion of mine. Band is cuff-style and adjustable. Back of ring is stamped 925. Silver is scratched from normal wear. Fits finger sizes 8 - 9 comfortably. Thank you for looking!
