4.5 overall Pearls are very nice- hoops have appearance more like stainless steel I ordered these fully expecting the hoop to be sterling silver. It might be but I could not find any stamp and the hoops have a look more like stainless steal to me. I am very familiar with SS and have quite a few SS jewelry pieces in my collection for comparison.I really give a 4.5 rating overall. I like all the colors of the pearls, which are a very nice size and really look like nice freshwater cultured pearls.I will wear these earring often.
