Renell Perry Navajo Sterling Silver Box Link Chain with Pink Stone, Agate? Penda

Pretty pendant that is oval in shape in a pretty pink. Looks like pink agate but I am not certain. The pendant is signed on the back and dated. The bezel is marked 925 and the end of the chain on the clasp it is also marked 925. The stone is in nice shape and measures about 1.5" wide by about 1" high not including the bezel. From the top of the bezel to the actual stone it is almost 3/4". The chain is a box link style and has a little clasp/closure. The chain measures about 16" long. The weight according to my scale is about 11 grams.
