Details: 4mm beaded smokey quartz with (1) 6mm beaded smokey quartz and (2) 14K Gold Filled beads Size: 6.5 inch elastic bracelet What is gold filled? Gold filled contains a solid layer of gold. It is made to last long and is a great alternative to solid gold. The chain is sweat and water proof making it great for your long term daily wear. For long lasting shine we recommend removing it in heavy salt water and chlorine or heavy duty skin and body care (ie peels, retinol, acids, etc.) *Each stone is naturally derived from the earth, making each stone vary in color, shape, and size. Please note that each stone will naturally vary and may adjust over longtime ware.
