18K Stamped Moroccan Made Yellow Gold/Sterling Silver 20" Chain

this is a sterling silver with yellow gold over. even tho its stamped 18k...it is NOT a all gold herringbone chain...not considering what I paid for them. If it was the price would be like 8 times my actual listed price. These are a weighty chain...plain herringbone 20". Ive been wearing another one from the lot for 2 weeks straight with no loss of color. Cleaning nightly with a jewelry cloth.
