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.

Poor quality
Color: Dark Blue
Purchased these in Aug ( it’s Oct now) only worn them maybe 3 times and already broke. They are cute to look at but quality is lacking. And I am very easy on my jewelry I never sleep or shower in any jewelry.

Nice bracelet set, very cutesy
Wife says: They are nice, the yellow is a little darker than other bracelets I own but it’s still nice, worn them like 5 times now and they are exactly the same, I do store them in little plastic ziplock baggies when I take them off though so they can last longer without tarnishing
