Pretty in pink, this tourmaline birthstone necklace is a stunning choice for an October birthday! The tourmaline coloured cubic zirconia crystal is 4mm and hangs on a gold plated sterling silver diamond cut curb chain. This chain is 0.6mm thick so it's fine and dainty and it measures 16+2 inches. Having the option to wear it at two different lengths is ideal if you aren't too sure how long the recipient likes their necklaces to be! 925 is stamped for sterling silver and it weighs 0.8g.
