Vintage Southwestern Tiger Eye Onyx Inlay Slider Pendant Necklace

Nicely made sterling silver slider pendant is marked Sterling and features a Southwestern geometric pattern of Tiger Eye and Black Onyx inlay.  It measures 1 1/8 inches, including the slider bail, by 3/4 inch wide and it is on an 18 inch sterling silver box chain.  The necklace weighs 10.7 grams and I will point out that there is a small diagonal scratch in the horizontal inlay on the right side of the pendant.  It is very minor and can only be seen at certain angles.
