Please consider after viewing the profile. This is an unused necklace purchased at Chahane, stored in a zippered bag. I selected "Men's" for the category because it was in the men's accessories section, but I think it can also be used as a women's accessory. I believe the stone is turquoise. I am not an expert, so I apologize if I am mistaken. Please judge from the photos and consider before purchasing. The length of the cord can be adjusted. There may be a difference in color between the photos and the actual product. Although it is unused, it has been stored at home for a while, so please consider before purchasing.
