This dazzler is made with a beautiful Swarovski crystal pendant as it's main focus and is accompanied by smaller Swarovski crystals, Czech glass and vibrant glass pearls. It hangs on a 20 inch chain and ties in the back with a toggle clasp. It can be lengthened or shortened upon request. All my silver and gold chains are tarnish resistant and hypo allergenic (not only nickel and lead free but also enamel covered to prevent allergies and tarnishing).
