"RJS" marking on Taxco bracelet

[veggietoo]

Hello! I have acquired this inlaid bracelet, and would greatly appreciate any help in identifying the maker. I believe the maker is identified by the initials "RJS". These initials are enclosed in a circle of the words "Taxco Mexico", with possibly 3 very small, unreadable marks at the "6 o'clock" position of the circle. Below that circle the word "Mexico" is stamped. Below that "925" is stamped. The inlay appears to be turquoise in the two larger outer areas, with possibly "onyx" in the dark area to the left of center, and perhaps "mexican jade"...or at least a green inlay...in the area to the right of center. Again, thanks much for any help! I'm a beginner, and I hope I've done this correctly! :)
