Sterling silver, turquoise, and coral ring!!!

There are no stamps or markings on it, but my jeweler told me that it’s sterling silver. It appears to be sterling, based on the patina. Gemologist confirmed that it’s turquoise. Ring size is 6.5–see last photo. Super beautiful ring with lovely stone/coral! Stay tuned!!! #tutquoise #spiny #oyster #coral #silver #ring
