Need some help!!
Color: GOLD METAL
Not great, and was hoping you’d give me a refund/ new bracelet. Got it for my mom a year ago for my mom and it came apart at the front.
I can return if you need it but she really loved it..
Thank You

Cute and Comfortable!
Color: GOLD METAL, Color: GOLD METAL
I love this Kendra Scott stackable gold bracelet! It’s lightweight, comfortable, and looks beautiful whether I wear it alone or layered with other pieces. The gold finish has a nice shine without looking too flashy, and it feels high-quality. It’s become one of my go-to everyday accessories!
