Bella Lili is a jewelry brand owned/operated by Autumn Phillips. She makes all the jewelry herself and everything is either in very limited quantities or one of a kind. I purchased this on Etsy back in 2010. Here is the original listing description of this piece: Promise of Violence is brass knuckles inspired with a solid black jewel. Its achingly beautiful. A soft caress and the whisper of sound, you are given the promise of violence before she strikes. She is beautiful with an edge. This necklace was made for fearless women who love to make statements. Sometimes the loudest voice is one that never utters a word. Promise of Violence is a limited edition series. Each necklace is one of a kind. This version features a large, sold jet black swarovski marquise jewel. All the stationary metal joints have been soldered. This is a heavy piece with a lot of movement and with just the right amount of sparkle amid industrial edges. :) It's phenomenal! Measurements: 16" with a 3" extender Jewel 1 1/4" by 5/8" approx 🦇 Thank you for checking out my listing! 🦇 🦇 Please ask all questions prior to purchasing 🦇 🦇 All sales are final 🦇
