Necklace & earrings set

Given to me as a gift and I don't have much information about this beautiful jewelry set. 🌺. Silver toned necklace and earrings with beautiful crystal flower details. Like new condition, worn once just not my style but gorgeous! Not sure if this is genuine silver or gold as there is no markings on either item. This can be costume jewelry but the crystals look expensive. Very sparkly. Offers are welcome. Will ship in a box.
