Worth buying
Color: Red
the earrings are much better in person. The images don't do justice to the quality of this product. The color is vibrant, the border is shiny and a nice size. They are definitely worth the money. Easy to wear, light weight, got many compliments on them.

Elegant and Beautiful Earrings – Just ProbablyNot for Sensitive Skin
Color: White, Color: White
These earrings are absolutely beautiful and elegant, with a timeless design that perfectly complemented the necklace I already own (different brand). They added a touch of sophistication and would be a lovely addition to any jewelry collection. Unfortunately, after trying them on, I noticed some redness on my ear, and since I have sensitive skin, I wasn’t sure if it was due to the clasp pressure or a reaction to the material. Out of caution, I decided to return them. That said, I would still highly recommend these earrings to anyone without sensitive skin—they really are stunning in person.
