Crystal? The cut is beautiful, so I think it will look great in the coming season! Length: Approximately 45cm, excluding the top. To put it around your neck, you'll need to detach the clasp. This was from some apparel brand, but I forgot which one. I have other necklaces for sale too! ↓ #LuckyBundleDiscount I haven't used it much, so there are no noticeable scratches, etc., but it's a recycled item, so please refrain from purchasing if you are concerned about minor details.
