HSN Sterling Silver Smoky Quartz & Diamond Pendant

Stamped 925. In great condition except for one missing stone. Discounted price for this. Does not show up in photos. Did not notice it till I looked up close and used the magnifying glass. Don’t know the weight of the stones, but diamond weight is at least .25 ct. About 1 1/4” long. For pendant only. No necklace included. Missing stone is the 2nd piece down from the top on the right hand side.
