This necklace is made using natural stones so the colors and sizes may vary slightly from what's pictured above. The chain and components are 14k gold filled so when taken care of should last for many years. The necklace is 13" long with a 2" extender. Picture 2 shows you the range of 13"-15". The bar length is approximately .5 of an inch long. Each necklace is packaged in a jewelry bag and comes with a card (pictured above) detailing the stone and its properties.
