Turquoise Silver Women's Ring

Elegant turquoise ring set in silver, perfect for adding a pop of color to any outfit. So pretty. Like new condition. Size 6 1/2 I’m not sure what type of turquoise I’m not sure if it is turquoise. The band is a thick silver band and the back of the ring is very beautifully done in silver but the stone I’m not sure what it is. It may be a turquoise because where I bought it all they sell are genuine stones, gemstones, and semi precious stones like citrine and topaz, but it may be that the stone has a treatment over the stone. I really don’t know but I paid $200 for it about 10 years ago. It looks brand new.
