APM Monaco necklaces are made with sterling silver and 18k gold-plated. The crystals are cubic zirconia. This necklace is fully adjustable with a sliding clasp. The condition is like new. I had the necklace sent for cleaning and replating with APM Monaco after the two year mark. It should last at least another two years like new. If you like APM Monaco, check out my other listings. The pouch with box and ribbon will be included!
