its a 14K Gold necklace, 10K Gold setting with Tanzanites (purple bit), Diamonds (clear bit) and then Mother of Pearl (white bit). The necklace is 45cm long minus the clasps so it’d be 5mm plus longer inc clasps.
Theres a tag in the box and apparently it $359.00 RRP. so leave the tag in the box and she will think you’ve spent loads on her
Stunning bit of kit and i’ll remind you its brand new never been worn
