Cute starter necklace!
My granddaughter showed her interest in "mood" jewelry so I bought her necklace to wear along with her 1st jewelry box. The charm works well and quickly changed color to fit her mood. The necklace chain is okay but I'm probably going to buy her a stronger one. Otherwise she enjoys it

very beautiful!! love itttt!!!
i absolutely love this!! it’s more like children’s jewelry, so don’t expect it to be like high-value materials. the clasp is a little small for my hands, but it’s made for children, so i’m not too worried about it. i could always switch clasps later. the little loop that holds the locket to the chain on mine broke, but i can always fix that, so no biggie! i love that through out the day, i can look at it and it might be a different color! i absolutely love the idea of thisss!! i had printed out pics of my best buddies and put them in the locket! looks nice! (although the ink when printed is a little off on coloring - but i can always change the photos later)

Nice Gift!
My daughter wanted to get her best friend a necklace before she and her family move away. We picked out the two piece "best friends" heart necklace. I was pleasantly surprised that it not only came nicely wrapped in plastic but in a nice little gift box, as well. It seems to be decent quality. It's got some weight to it and doesn't seem like it will come off the chain or break real easily. It also included a mood explanation card at the bottom of the box. My only complaint is that one of the halves seems to change when you are not touching it and the other half doesn't seem to want to change when you are holding it. We've only played around with one half, since the other half is a gift, but the one we took out doesn't want to change any color other than blue to black (when we put it in the freezer!). The half that we haven't taken out of the plastic has just randomly turned blue to green to yellow to red. It's cool but.... odd. I thought it was suppose to be body temperature sensitive. In any case, they are very cute and I am happy with my purchase.

Cute! Fun Gift.
Here’s a Timelapse video of the pendant going from green to blue & back again. Doubt it would show the whole array of “mood” colors but the colors it does make are pretty. For the price I feel the quality is quite good.

Tiny
The pendant (star) is only half the size that the description says it is. The description says that the dimensions are over an inch wide and it is obviously not that big. I bought it to use the pendant for jewelry making- wanted it to be a pendant for a necklace but it is too small, unless I use tiny beads. I may order another one and make dangly earrings, which I think would work well. It is about the right price for a necklace with a very small pendant.

Good for sharing with friends.
My grandson, who is on the Autism spectrum wanted this to share with two of his school friends. We got it for him for Christmas and he was very happy and excited when he got it.

Adorable best friends set
This was amazing! I got them for my children and their cousins There aren't a lot of sets that have four in them & they all loved their necklaces, especially because they're "mood necklaces. They got a real kick out of that. All of the parts are metal and they look like they're going to last for a while. If you have four children that all want best friends necklaces this is the set to get!
