These are mismatched earrings. I liked the flower shape and the bead material. The material is unknown. It is not silver. I bought them for ceremonies, but I haven't had many opportunities to wear them, so I'm selling them. Short one: about 4.5cm, Long one: about 6cm The earring backs are also flower-shaped. I felt they didn't sit quite right when I wore them, so I sometimes used silicone earring backs instead. I will also include unused silicone earring backs. Thank you.
