Very Pretty, Well Packaged, Good value
Style: L, Color: Rose Gold
Bought these for my twin granddaughters golden birthdays. They're only 7 so was afraid to buy real gold they might lose. These are lovely. I love that personalized initial. And they can wear them for a long time but if they lose them it's no biggy at this great price.

Love it!
Color: Beige
Beautiful jewelry display that was super easy to put together! It’s big enough to hold my pieces while also being compact enough to not take up much space. It’s a very sturdy & stable piece that’s aesthetically pleasing to the eye. And the gold & cream color screams luxury!
