Why do you think that the necklace is 825 silver? The smaller mark is an called an eagle mark and it looks like it has a three in the middle. Eagle marks are put on Mexican silver in part as to designate the fineness of the silver as at least sterling or 925. There is also a 925 in the circle around what look like the Initials TAM. That also means that the silver is sterling. TAM is the makers mark and can be found as a silver maker with an eagle three designation in Hougarts book of Mexican Silver Hallmarks. There are different styles of eagle marks and your photo isn't clear, but it looks like a later eagle and they were in use from 1948 - 1980. From what I can see it looks like a nice design. If I were to sell it I would want to get three times silver weight at 1 dollar a gram ( so 85x3= 255) unless it's a collected designer or enameled or unusual then I would adjust the price accordingly. Hope this helps

Re: Mexican silver necklace
It was difficult to discern if the marking was an "8" or a "9" in my comment that it is 825 silver. Commentor's expertise is much appreciated.
