32-inch faceted quartz (rock crystal) necklace, long beads, natural focus

A classically beautiful necklace of rock crystal quartz--not glass--faceted to draw light in. Rock crystal will show natural striations under magnification, and it stays cool to the touch longer than glass does. It is also heavier, as a rule. This necklace weighs 105 grams. From an estate to my nonsmoking, pet-loving home, where I cleaned it lightly. Condition is vintage excellent; I cannot find any flaws or chips, but there might be some general wear. The clasp is silver-tone it is not silver. Thank you for looking!
