Beautiful Religious Virgin Mary Sterling Silver Antique- Vintage Pendant Necklace w chain Cobalt Blue Guilloche enamel & Marcasites

Gorgeous sterling silver vintage/antique religious pendant it is made with a lovely multi tone cobalt blue Guilloche enamel Surrounded with good size marcasites. the size is not very large, but to me a perfect dainty size, not too big and not too little. I am honestly not sure what is portrayed on the backside I can’t tell if it is a scene like a nativity scene or what please see photos and decide for yourself. This could be a reversible pendant. This pendant will come with a solid sterling silver chain. Please see photo for approximate measurements. Items can appear larger than in reality. this could make a wonderful gift
