Those born in October are lucky enough to have both tourmaline and opals as their birthstone, so they are sure to appreciate this sterling silver necklace with its tourmaline coloured cz crystal. The diamond cut curb chain is supplied in lengths from 14 to 32 inches so that options are available for any age and style preference. Threaded along this delicate necklace is the 3.5mm round cut crystal, set in four claws, hanging from a jump ring. This gives the pendant an overall height of 10mm and it is 4mm wide x 3mm deep.
