925 silver turquoise green color cigar band 8.5

Artesian 925 silver turquoise green color stone cigar band sz 8.5, fits sz 7-7.5 as heavy wide shank. photos added part of description. My attempts at narrowing down the stones origin (as not to assume India), led me to a vast array of acceptable turquoise production techniques used to replicate them over hundreds of years even. It is vast & varied. Perhaps Howlite Turquoise, but cannot say for sure. I do suggest Google: turquoise variations yourself (+ very interesting) it is stamped 925
