Quality is Okay
Color: 11-Nov-Lab Grown Citrine, Style: H
I ordered this for a Christmas present and the pendents are very small. The price as good but didn't think the quality was great. It does come in a nice gift box.

Super Cute & Well-Packaged
Style: M, Color: Gold, Style: M, Color: Gold
I bought this for my 6-year-old niece and it was super cute! I love how it was packaged and came with a notecard you could right on. I also love the message that it comes with and was something I wanted my niece to know and remember. It’s simple, the perfect size, and a great little gift!

Cute
Necklace is so cute. And perfect for a little girl! It is a little cheesy , but it wasn’t for my niece. It’s very simple but makes a statement. Doesn’t seem to fade and seems strong against wear!
