Vtg Natural Stone Beaded 925 Sterling Silver Toggle Clasp 18" Necklace

Natural Stone Beaded 925 Sterling Silver Toggle Clasp 18" Necklace. Clasp is not marked that I can see but I tested it, and it tests positive for 925 Sterling Silver. Vintage Necklace is in excellent condition. I am not sure what stones these are, but a google search most often brings up jasper stone. Neutral green, cream and light brown colors.
