Visit Key West Local Luxe to see a truly unique inventory of 2000 Year Old Ancient Roman Glass jewelry. The majority of the material, as with these earrings, was unearthed in Israel at ancient archaeological city sites. The iridescent colors in the glass occur as a result of chemical reactions to the elements in the soil over the centuries. Each piece is hand cut from different fragments making each piece truly one of a kind. All of the silver is a beautiful bright Sterling Silver, and here, these earrings have terrific 18k Gold bezel that the glass is set in.
