These are vintage items I believe - had in my jewellery box I think since the 1990's if not earlier and not worn much at all

The are matching in design - both are stamped 375 ITALY - there is a smaller hallmark on each item that probably identifies the maker and year but I am not able to clarify even with magnification (I think there is an A or triangle after the 375 and then another symbol)

Beautiful flat snake weave into V - yellow and rose gold - and either a white gold or silver (sorry not sure on this)

Lovely condition - clasps are good order. Very slight kink in the necklace but this flattens out when worn - think it's just the way it's been lying in jewellery box, can't see any signs of damage or repairs. Lovely items. 

Weight is 4 g both sets 

Bracelet is approx 17cm or 6.5 inch - see photo

Necklace has a 20cm drop - see photos
