Very pretty
My daughter loves these. Another take on a dangle biggie earring. Love the beaded huggie style and the solid brushed gold with stone in the center of the heart. Lots of movement. Decent quality. Fit is comfortable and easy on and off. Great size. Good value. She has worn them often so far.

Small Gold Heart Earrings
These earrings are nice but I did mark it down 1 star due to it was hard to clasp them closed. They are light in weight so they won't weigh down your ears.

Elegant, Lightweight & Eye-Catching
Color: Green, Size: 3 clover, Color: Green, Size: 3 clover
These are really nice earrings—long and elegant without feeling heavy at all. They’re super lightweight, so they’re comfortable to wear all day. The design is eye-catching and adds a nice statement without being too much. The green detail is pretty and gives them a unique look. They hang nicely and move just enough to catch the light. Great quality, stylish, and easy to wear.
