JTV Sterling and turquoise (?) ring-size 5

Beautiful turquoise oval ring with intricate sterling silver detailing. Perfect for adding a pop of color to any outfit. Southwest Style By Jtv(tm) 18x13mm Oval Turquoise Cabochon Solitaire Sterling Silver Ring - SWE1450-5 Size: 5 The ring is sterling silver, I am trying to figure out if the turquoise is genuine. The above statement is taken directly from the invoice by JTV so I’m thinking it might be genuine turquoise. There is a small white dot a size of a needle on the stone, which could be perceived as a flaw, but if it is a natural turquoise stone, they do have variations. Although the tag has been removed, it is new, never worn.
