Not being a jewellery expert but I can make this observation on the jewllery in question. OVERPRICED. No wonder your sales have plummeted and for the other jewellery description. I hope you realise that by stating its layered and 75 mil think it should be 3 inches thick in 18 ct gold. I DONT THINK SO. you probably meant 75 microns, thats about 2 thousands of an inch thick. in other words ZERO gold value.

I think "75 mil" is a unit of some sort. I have only ever come accross the term online when reading tech stuff. It may be microns though.
