Platinum plated and zirconia white opal stones from shop called Cute Things Commin’ - I shop I discovered through Tik tok and Instagram. Pouch included. Length is 17.7in with 2.4in extender. Have only worn twice . The shop claims this is water-resistant and anti-tarnish but I haven’t had it long enough to confirm nor did I ever wear this in the water. The necklace is in brand new condition but I used the pouch more than a few times in order to carry a few small beauty items to work, so you will notice 2 tiny spots on the outside near the bottom from my clumsy self dropping acrylic nail glue. Do not want to touch it further so I will leave that up to you if you know how to remove. Other than that, the pouch is clean and the inside is very soft so it’s perfect for protecting the necklace. Will add extra layer of protection when shipping necklace so I will put the necklace in a protective bag that is sealed.
