You open the the shell and retrieve your pearl.
Then you place it in the enclosed necklace.
Bee loves it! Unfortunately, we had it three days when it mysteriously vanished. I was taking a lot of pictures that day and can pin point it to about a 10 minute slot which makes it even more frustrating. I quickly ordered a new online last night, luckily they are only a few dollars. I found mine on eBay. I'm sure we will find the old one as soon as the new one arrives.
