The Time Turner Twin Necklace Set comes in either silver and gold overlay. My daughter is a huge Harry Potter Fan, and when I saw this set, I couldn't have been happier. I had the opportunity to check out this duo set, and my ten year old daughter absolutely loves these necklaces. At first when I received these, I thought that they were cheaply made, and wondered at how durable these were; however the durability really surprised me. They have lasted to my surprise for well over a month with wearing the time turner several times a week. My daughter isn't graceful to say the least, but I am impressed that they have lasted this long. I will be ordering another set in gold, so that she has two sets, should something happen to the first one. Overall I am very satisfied with this.
