The primary stones appear to be Polki , which are uncut diamonds. However, given the evenness of the stones and the overall look, they are likely high-quality imitations made of glass or cubic zirconia, designed to mimic the look of Polki. The earrings complement the necklace, featuring a similar design with multiple "Polki" stones in connected settings. They are likely drop or dangle earrings. This set is versatile and could be worn for various occasions from formal events to more casual gathering.
