A crystal or gem stone point of your choice hangs from a 34" oxidized sterling silver ball chain. The chain has a black tubular lava stone at the nape to add your favorite essential oil which will diffuse the scent all day. The points will vary in size and color as they are all natural. They range from 1 1/2" to 2" long and approximately 1/2" wide. These necklaces are great for layering.
